                     PENSECO FINANCIAL SERVICES CORPORATION
            150 North Washington Avenue, Scranton, Pennsylvania 18503


PROXY STATEMENT MAILED MARCH 15, 2005 FOR THE ANNUAL MEETING TO BE HELD TUESDAY,
MAY 3, 2005,  AT 2:00 P.M. AT THE CENTRAL CITY OFFICE OF PENN  SECURITY BANK AND
TRUST COMPANY LOCATED AT 150 NORTH WASHINGTON AVENUE, SCRANTON, PENNSYLVANIA.


     INTRODUCTION Penn Security Bank and Trust Company (hereinafter, the "Bank")
is  a  wholly-owned   subsidiary  of  Penseco  Financial  Services   Corporation
(hereinafter, the "Company"). This Proxy Statement, while prepared in connection
with the  Annual  Meeting  of  Shareholders  of the  Company,  contains  certain
information relating to the Bank which will be identified where appropriate.


     REVOCABILITY  OF PROXY Any person  giving the proxy  herein  solicited  may
revoke  it at any  time  prior  to its  being  voted at the  annual  meeting  by
submitting a later dated proxy, or by contacting the Secretary,  P. Frank Kozik,
in writing prior to the meeting indicating the shareholder's intention to revoke
the proxy.  Execution of the accompanying  proxy will not affect a shareholder's
right to attend the meeting and vote in person.


     PERSON MAKING THE  SOLICITATION  The  solicitation  is made by order of the
Board of  Directors  of the  Company,  the  cost of  which  will be borne by the
Company.  Solicitation  is being  made  primarily  by use of the  mail,  but the
management may solicit proxies by telephone or personal interview.



     VOTING  SECURITIES  &  PRINCIPAL  HOLDERS  THEREOF  The number of shares of
common  stock  outstanding  and  entitled  to vote at the  annual  shareholders'
meeting is 2,148,000 as of this date.  Only those  shareholders of record at the
close of business on March 4, 2005 shall be entitled to vote.  The presence,  in
person  or by  proxy,  of the  holders  of a  majority  of the  total  number of
outstanding  shares and entitled to vote is necessary to  constitute a quorum at
the annual shareholders' meeting.

     In the election of Directors, each shareholder has cumulative voting rights
and is entitled to cast in the  aggregate  as many votes as the number of shares
owned,  multiplied  by the number of  Directors  to be elected  and to cast such
votes  for  one  candidate  or to  distribute  such  votes  among  two  or  more
candidates.  The  candidates  receiving  the  highest  number of votes up to the
number  of  Directors  to be  chosen  shall be  elected.  The  proxy  permits  a
shareholder to vote for or withhold his vote from the election of Directors. The
proxy holders named on the Proxy will vote for the Board's  nominees  unless the
shareholder  has withheld his vote from some or all of the nominees.  Such proxy
holders may exercise  discretionary  authority to cumulate votes in the election
of Directors by  distributing  the votes they are  authorized  to cast among the
Board's  nominees in order to elect the largest  possible number of them (in the
event there is a nominee or nominees other than the Board's  nominees),  and, to
the extent  possible,  in order to cast the same  number of votes for each Board
nominee. On other matters, each share of stock entitles the owner thereof to one
vote. Abstentions and broker non-votes are not included as votes cast.

     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors,  certain of its executive  officers and persons who own more than ten
percent of a registered class of the Company's common stock (currently there are
no such  persons),  to file reports of ownership  and changes in ownership  with
respect to shares of the Company's common stock  beneficially owned by them with
the Securities and Exchange Commission and to furnish the Company with copies of
all forms that they file. Based solely on its review of the copies of such forms
received by it, or written  representations  from certain reporting persons that
no such forms were required for those persons,  the Company believes that during
fiscal 2004 all required reports were filed on a timely basis.

     The  following  table sets forth,  as of February 25, 2005,  the amount and
percentage  of the  common  stock  of the  Company  beneficially  owned  by each
Director and all Principal  Officers and Directors of the Company as a group. No
shareholder owns 5% or more of the Company's stock.

                          BOARD AND COMMITTEE MEETINGS

     The Board of  Directors  met 29 times in 2004.  All  Directors  attended at
least 75% of the  total of the Board of  Directors  meetings  and the  committee
meetings of which they were members.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     The  Bank  employed  Chad J.  Hazelton  in the  non-executive  position  of

2004.

                                 AUDIT COMMITTEE

     The Company  has a standing  Audit  Committee  of the Board  consisting  of
Directors Edwin J. Butler,  Russell C. Hazelton,  James G. Keisling and P. Frank
Kozik, none of whom are operating  officers of the Company.  The Company's Board
of Directors has adopted a written  charter for the Audit  Committee.  A copy of
the  charter,  which sets forth the  duties  and  responsibilities  of the Audit
Committee,  was filed with the definitive proxy relating to the Company's Annual
Meeting of Shareholders, held May 6, 2003. The charter gives the Audit Committee
the authority and  responsibility for the appointment,  retention,  compensation
and oversight of our independent auditors,  including  pre-approval of all audit
and non-audit services to be performed by our independent auditors. The Board of
Directors of the Company has determined  that all members of the Audit Committee
are  "independent  directors",  as defined in Rule 4200 (a) (15) of the National
Association of Securities Dealers, Inc.

     Meetings of the Audit Committee are held approximately once each quarter to
discuss the quarterly reports of the Company's

                                      -5-



Internal  Auditor  and  management's  response  thereto  and report to the Board
thereon.  At these  meetings,  the Committee has the opportunity to discuss with
management  the adequacy of the  Company's  internal  controls and the financial
reporting  process.  It may also  discuss  these  matters  with the  independent
auditors and with appropriate Company financial personnel. The Committee reviews
our financial  statements and discusses them with management and the independent
auditors  before those  financial  statements  are filed with the Securities and
Exchange Commission. The Committee met six times in 2004.

     The  Committee  also meets  privately  with the  independent  auditors  and
periodically  reviews their  performance and independence  from management.  The
independent  auditors  have  unrestricted  access  and  report  directly  to the
Committee.


                        AUDIT COMMITTEE FINANCIAL EXPERT

     The  Sarbanes-Oxley Act of 2002 requires the Company to disclose whether or
not its  Audit  Committee  has,  as one of its'  members,  an  "Audit  Committee
Financial  Expert",  as that term is  defined  by the  Securities  and  Exchange
Commission (SEC).

     The Board of Directors has elected not to designate any member as an "Audit
Committee  Financial  Expert".  The audit program at our organization has always
been strong. We have our own,  full-time internal auditor reporting to the Audit
Committee who has a staff of four full-time assistants. Our financial statements
are audited by an  independent  registered  public  accounting  firm,  which has
received  approval from the Public Company  Accounting  Oversight Board to audit
financial reports of SEC reporting companies.  In addition to that, since we are
a banking company,  our bank, Penn Security Bank and Trust Company,  is examined
every  year on an  alternate  basis by either  the  Pennsylvania  Department  of
Banking or the Federal  Deposit  Insurance  Corporation  and our parent  holding
company  is  examined  yearly by the  Federal  Reserve.  Our  four-member  Audit
Committee  includes three members with  substantial  education and experience in
accounting and financial management,  of which, two are Chief Executive Officers
of companies and one is a former Executive  Vice-President  of our organization.
The Audit  Committee,  as well as the entire  Board of  Directors,  are  ethical
people  who will  act  responsibly  if  anything  is  wrong.  We think  that our
Committee members acting together have the expertise,  information and advice to
assure that our financial statements are fairly presented.


                                OTHER COMMITTEES

     The Company has a standing  Compensation  Committee of the Board consisting
of Directors Edwin J. Butler, P. Frank Kozik, Robert W. Naismith, Emily S. Perry
and Otto P. Robinson, Jr. The committee recommends to the Board of Directors the
compensation  to be paid to the  Executive  Officers  of the  Company as well as
general guidelines for compensation of the employees of the Bank. Three meetings
of the committee were held in 2004.

     The Company does not have a standing Nominating Committee of the Board. Due
to the size and local  nature  of the  Company,  as well as the fact that  Board
vacancies  occur  very  infrequently,  all  members  of the  Board of  Directors
participate  in the  identification,  recruitment  and selection of nominees for
election as directors of the Company.


                             DIRECTORS' COMPENSATION

     During  2004,  Directors  received  an annual  retainer of  $9,000.00  plus
$600.00 for each Board meeting  attended and $250.00 for each committee  meeting
attended.  Directors  who are  operating  officers of the Company do not receive
fees for committee meetings attended.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Company's  compensation  program for executive officers is administered
by the  Compensation  Committee  of the Board of  Directors  ("Committee").  The
Committee  makes  recommendations  to  the  Board  of  Directors  regarding  the
compensation arrangements for executive officers,  including the Chief Executive
Officer.  The compensation program for the Company's executive officers consists
of a base salary,  annual cash bonus,  and other  perquisites.  In 2004, Otto P.
Robinson, Jr., the President and Chief Executive Officer, was the only executive
officer to receive a perquisite, which was the use of a Bank owned automobile.

     The   Committee   determines   executive   base   salaries   by   level  of
responsibility,  individual  performances  and,  to  a  lesser  degree,  Company
performance, as well as by the need to provide a competitive package that allows
the Company to retain key executives.  After reviewing  individual  performances
for  the  year  and  available   information  on  salaries  at  other  financial
institutions of similar size, the Chief Executive Officer makes  recommendations
to the Committee concerning the base salaries of other executive officers. Using
the same  review  process,  the  Committee  makes  recommendations  to the Board
regarding the Chief Executive Officer.

     Annual cash bonuses are intended to focus the efforts of executive officers
on the attainment of specific  annual  performance  goals which will promote the
overall  success of the Company.  The Chief  Executive  Officer  evaluates other
executive   officers  in  their   achievement   of  specific   goals  and  makes
recommendations to the Committee regarding bonuses to be awarded.  The Committee
recommends to the Board the annual bonus for the Chief  Executive  Officer based
to a large  degree upon the  financial  performance  of the  Company  using such
financial measures as earnings per share, return on average assets and return on
average equity. Mr. Robinson,  suffering a physical  incapacity during 2004, did
not accept a cash bonus for that year. The President and Chief Executive Officer
did not  participate  in the decision by the Board of Directors  relating to his
base salary.

and Chief  Executive  Officer.  Mr. Edwin J. Butler is a retired  officer of the
Bank. Mr. Robinson abstained from all voting regarding his own compensation.

                          REPORT OF THE AUDIT COMMITTEE

     We have reviewed the Company's audited  financial  statements as of and for
the year ended  December  31,  2004,  and met with both  management  and McGrail
Merkel Quinn & Associates,  independent  auditors,  to discuss  those  financial
statements.  Management has represented to us that the financial statements were
prepared in accordance  with  accounting  principles  generally  accepted in the
United States of America.

     Management  has  primary   responsibility   for  the  Company's   financial
statements and the overall reporting process,  including the Company's system of
internal  controls.   The  independent   auditors  audit  the  annual  financial
statements  prepared  by  management,  express an  opinion  as to whether  those
financial  statements  present fairly, in all material  respects,  the financial
position, results of operations and cash flows of the Company in conformity with
accounting  principles  generally  accepted in the United  States of America and
discuss with us their  independence  and any other  matters they are required to
discuss with us or that they believe should be raised with us.

     We have received from and discussed with McGrail Merkel Quinn & Associates,
the written  disclosure and the letter required by Independence  Standards Board
Standard No. 1  (Independence  Discussions  with Audit  Committee).  These items
relate to the Firm's  independence  from the  Company.  We also  discussed  with
McGrail  Merkel  Quinn &  Associates  any matters  required to be  discussed  by
Statement on Auditing Standards No. 61 (Communication with Audit Committees).

     Based on these  reviews and  discussions,  we  recommended  to the Board of
Directors  that the audited  financial  statements  be included in the Company's
annual  report on Form 10-K for the year ended  December  31, 2004 as filed with
the Securities and Exchange Commission.


                                                Respectfully submitted,
                                                MEMBERS OF THE AUDIT COMMITTEE

                             EMPLOYEE BENEFIT PLANS

     Principal  officers of the Bank  participate in the Bank's employee benefit
programs  on the same basis as all other  employees  and only  receive  the same
benefits as all other employees.

     Penn Security Bank and Trust Company  maintains a qualified defined benefit
retirement  (Pension)  plan for its employees  and  officers.  Directors who are
non-active  officers are not included in the plan. In 2004, the Bank contributed
$380,989.00.  Under the funding  method  employed  for this plan,  the amount of
contribution,  payment or accrual  in respect of a  specified  person is not and
cannot readily be separately or individually calculated for the plan.

     Remuneration for pension benefit purposes includes all earnings  reportable
as IRS Form W-2 wages for Federal income tax withholding purposes. Final Average
Compensation means the average  compensation paid to an employee during the five
consecutive  calendar years out of the final ten years of service which produces
the highest average.

     The above table of estimated annual  retirement  benefits is representative
of an employee  currently age 65 whose salary remained unchanged during his last
five years of employment and whose benefit will be paid for the remainder of his
life.  The benefits  payable  under the plan are subject to the maximum  benefit
limitations of Section 401 (a)(17) of the Internal Revenue Code.  Benefits based
on normal retirement at age 65 provided for an annual pension equal to 1% of his
Final Average  Compensation up to his Covered  Compensation,  plus 1 1/2% of his
Final Average  Compensation  in excess of his Covered  Compensation  per year of
Credited Service, not beyond his normal retirement date, with partial credit for
fractional  years.  Covered  Compensation  is determined in accordance  with the
Social Security Act as in effect at the time of the employee's final termination
of employment. Covered Compensation is the average annual wage covered under the
Social Security Act throughout the employee's  working  lifetime.  In accordance
with the Social Security Act, maximum Covered Compensation for the year 2004 was
$46,344.00.

     The  years of  creditable  service  as of  December  31,  2004 for  Messrs.
Robinson,  Grimm,  Moylan,  Kettel  and  Calpin  were  29,  25,  5,  34,  and  4
respectively.

     Supplemental  Benefit Plan Agreement.  Penn Security Bank and Trust Company
has entered into a  Supplemental  Benefit  Plan  Agreement  (the  "Plan")  dated
December 28, 1995 with a retroactive effective date of January 1, 1994, with Mr.
Robinson.  The  purpose  of the  Supplemental  Benefit  is to  grant  additional
benefits  in excess of those  accrued  in the  pension  plan due to the limit on
compensation  contained in Section 401 (a)(17) of the Code. The Plan is intended
to be an unfunded  excess  benefit  plan under  Section  (3)(36) of the Employee
Retirement  Income  Security Act of 1974 (ERISA).  The Plan provides that if Mr.
Robinson  retires from  employment  with Penn Security Bank and Trust Company at
his Normal  Retirement  Date, he shall be entitled to receive a benefit equal to
(a) the benefit  which would have  accrued  under the  provision  of the Pension
Plan, if such Pension Plan were  administered  without regard to the limitations
under Code Section 401 (a)(17),  less,  (b) the amount of the Normal  Retirement
Benefit  which he is entitled to receive  under the Pension  Plan. If he retired
from employment at his Early  Retirement Date, he shall be entitled to receive a
benefit equal to (a) the benefit  which would have accrued under the  provisions
of the  Pension  Plan  computed  in  accordance  with  Section  3.1 to his Early
Retirement  Date, less (b) the amount of his Early  Retirement  Benefit which he
would be  entitled  to  receive  under the Plan.  If Early  Retirement  Benefits
commence prior to his Normal  Retirement  Date,  the benefits  payable under the
Plan  and  the  Pension  Plan  shall  be  actuarially  reduced  for  such  early
commencement  to the extent  provided  under the terms of the Pension  Plan.  If
retirement is after his Normal  Retirement Date, he shall be entitled to receive
a benefit equal to (a) the benefit which would have accrued under the provisions
of the Pension  Plan,  computed in  accordance  with Section 3.1 to his Deferred
Retirement Date, less, (b) the amount of Deferred Retirement Benefit which he is
entitled to receive  under the Pension  Plan.  In no event will Mr.  Robinson be
entitled to receive total  benefits from the Plan and the Pension Plan in excess
of the benefit

                                      -9-




he would have  received  from the  Pension  Plan if the  limitations  under Code
Section 401 (a)(17) were not  applicable to the Pension  Plan.  If Mr.  Robinson
terminates  employment with Penn Security Bank and Trust Company for any reason,
the Accrued Benefit at the date of termination shall be valued and payable in an
aggregate  amount equal to his accrued  benefit.  Any such payments will be paid
from the Bank's general assets. If a Change of Control of Penn Security Bank and
Trust Company occurs, Mr. Robinson's accrued benefit shall be valued and payable
in accordance with the provisions stated above.  "Change of Control" shall occur
when any  person  other than the Bank  obtains  ownership  or voting  power with
respect to greater than 50 percent of the aggregate  value or voting  power,  as
applicable, of the Employer's capital stock.

     The Bank's  Retirement  Profit  Sharing Plan includes  employees as well as
officers.  Directors who are  non-active  officers are not included in the plan.
Under the plan, amounts voted by the Board of Directors are paid into a fund and
each employee is credited with a share in proportion to his annual compensation.
Upon retirement or death or termination or disability, each employee is paid the
total amount of his credits in the fund in one of a number of optional  ways. In
2004, the Bank contributed $60,000.00 to the Retirement Profit Sharing Plan.

     The Bank's Employee Stock Ownership Plan (ESOP), includes employees as well
as officers. Directors who are non-active officers are not included in the plan.
Under the plan,  amounts  voted by the Board of Directors are paid into the ESOP
and  each  employee  is  credited  with a  share  in  proportion  to his  annual
compensation.  All contributions to the ESOP are invested in or will be invested
primarily in Penseco Financial Services Corporation stock. In 2004, the Bank did
not contribute to the ESOP. Distribution of a participant's stock account occurs
upon retirement or death or disability or termination of employment.


               TRANSACTIONS WITH DIRECTORS AND PRINCIPAL OFFICERS

     The  Bank has  had,  and may be  expected  to have in the  future,  banking
transactions  in the  ordinary  course of  business  with  Directors,  principal
officers,  their immediate families,  and affiliated companies in which they are
principal  stockholders  (commonly referred to as related parties),  on the same
terms, including interest rates and collateral,  as those prevailing at the time
for comparable transactions with others and did not involve more than the normal
risks of collectability or present other unfavorable features. These persons and
firms  were  indebted  to  the  Bank  for  loans  totaling   $9,503,267.54   and
$6,066,296.02  at  February  1, 2005 and 2004,  respectively.  Such  loans had a
maximum  unpaid  balance in the  aggregate of  $9,474,033.37  and  $5,732,323.66
during the years ended  December 31, 2004 and 2003,  respectively.  In addition,
during 2004 and 2003, the Bank had outstanding standby letters of credit for the
accounts of related parties in the amounts of $6,932,107.21 and$6,352,877.00.

     In this Proxy Statement, the term "officer" means the President,  Executive
Vice-Presidents, Senior Vice-Presidents,  Vice-Presidents,  Treasurer, Secretary
and Controller.

                      SHAREHOLDER RETURN PERFORMANCE GRAPH

     The following line graph sets forth comparative  information  regarding the
Company's  cumulative  shareholder return on its common stock over the last five
fiscal years.  Total shareholder  return is measured by dividing total dividends
(assuming  dividend  reinvestment)  plus share price  change for a period by the
share price at the beginning of the investment period. The Company's  cumulative
shareholder  return  based  on an  investment  of $100 at the  beginning  of the
five-year period beginning December 31, 1999 is compared to the cumulative total
return of the S & P 500 Index  ("S & P 500")  and the SNL  Securities  Northeast
Quadrant Pink Sheet Banks Index ("Pink Banks"),  which more closely reflects the
Company's  peer group.  The yearly points marked on the  horizontal  axis of the
graph correspond to December 31st of that year.

                       OUR RELATIONSHIP WITH OUR AUDITORS
                    Independent Registered Public Accountants

     The Audit  Committee  has selected  McGrail  Merkel  Quinn and  Associates,
Certified Public Accountants and Consultants, to conduct an independent audit of
the financial  statements  of the Company for the year 2004,  and it is expected
they will be selected for the year 2005. Representatives of the Firm as expected
to be present at the meeting and will have an opportunity to make a statement if
they so desire and will be available to respond to appropriate questions.

     The fees billed by McGrail Merkel Quinn and Associates during 2004 and 2003
were as follows:

                              2004           2003
                              ----           ----
Audit Fees                  $ 57,200        $50,000
Audit-Related Fees            20,100         16,500
Tax Fees                       6,000          8,000
All Other Fees                     -              -

                                      -11-



     The  amounts  shown for  "Audit-Related  Fees" were for audits of  employee
benefit  plans and student  loans.  The amount shown for "Tax Fees" were for tax
return review and Federal and State tax advice.

     Under its charter,  the Audit Committee must pre-approve all engagements of
our Independent Auditors. The Audit Committee,  prior to retaining the Auditors,
will evaluate known potential engagements of the Independent Auditor,  including
the scope of the work  proposed  to be  performed  and the  proposed  fees,  and
approve or reject each  service,  taking into  account  whether the services are
permissible  under  applicable  law and the  possible  impact of each  non-audit
service on the  Independent  Auditor's  independence  from  management.  At each
subsequent  Committee  meeting,  the  Committee  will  receive  updates  on  any
non-audit services actually provided by the Independent  Auditor, and management
may present additional services for approval. The Committee has delegated to the
Chairman of the Committee the authority to evaluate and approve  engagements  on
behalf of the Committee in the event that a need arises for pre-approval between
Committee  meetings.  If the Chairman so approves any such engagements,  he will
report that approval to the full Committee at the next Committee meeting.

     Since  the May 6,  2003  effective  date  of the  Securities  and  Exchange
Commission  rules stating that an Auditor is not  independent of an audit client
if the services it provides to the client are not  appropriately  approved,  all
engagements of McGrail  Merkel Quinn and Associates  were approved in advance by
the Audit  Committee,  and none of those  engagements made use of the de minimus
exception to pre-approval contained in the Commission's rules.


                                Internal Auditor

     Mr. Robert P. Heim was  re-elected  by the Board of Directors  this year to
the  position of Director  of  Internal  Audit.  Mr. Heim will be present at the
annual meeting to respond to any appropriate questions.
