PROXY STATEMENT MAILED MARCH 21, 2003 FOR THE ANNUAL MEETING TO BE HELD TUESDAY,
MAY 6, 2003,  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 7,  2003  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
proxyholders  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
proxyholders  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 2002 all required reports were filed on a timely basis.


     The  following  table sets forth,  as of February 28, 2003,  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.

             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 2002, 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.

                                     - 6 -



     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's cash bonus for 2002 resulted from the Company's
favorable  performance  measures of $3.14  earnings  per share,  1.37% return on
average  assets and 11.79%  return on average  equity.  The  President and Chief
Executive  Officer did not participate in the decision by the Board of Directors
relating to his base salary and annual cash bonus.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 2002, the Company  employed Otto P.  Robinson,  Jr. as its President
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

     The Audit Committee has reviewed the audited  financial  statements for the
year ended December 31, 2002 and has discussed the audited financial  statements
with  management.  The Audit Committee has also discussed with McGrail,  Merkel,
Quinn  and  Associates,  the  Company's  independent  accountants,  the  matters
required to be discussed by Statement on Auditing Standards No. 61 (having to do
with  accounting  methods used in the financial  statements).  In addition,  the
Audit  Committee  has  received  the  written  disclosures  and the letter  from
McGrail,  Merkel, Quinn and Associates required by Independence  Standards Board
Standard  No. 1 (having  to do with  matters  that could  affect  the  auditor's
independence),  and has discussed with McGrail, Merkel, Quinn and Associates the
independent  accountants'  independence.  Based  upon these  actions,  the Audit
Committee  recommended  to the  Company's  Board of  Directors  that the audited
financial  statements be included in the Company's  Form 10-K for the year ended
December 31, 2002 for filing 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 2002, the Bank contributed
$202,119.00.  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 2002 was
$39,444.00.

     The  years of  creditable  service  as of  December  31,  2002 for  Messrs.
Robinson,  Grimm,  Moylan,  Calpin  and  Kettel  were  27,  23,  3,  2,  and  31
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 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
2002, the Bank did not contribute to the Retirement Profit Sharing Plan.

                                     - 8 -



     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 2002, the Bank
contributed  $140,000.00  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   $4,750,753.98   and
$6,006,575.50  at  February  1, 2003 and 2002,  respectively.  Such  loans had a
maximum  unpaid  balance in the  aggregate of  $5,499,675.65  and  $7,047,864.67
during the years ended  December 31, 2002 and 2001,  respectively.  In addition,
during  2002,  the Bank  issued a standby  letter of credit for the account of a
related party in the amount of $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, 1997 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.

                                    AUDITORS

     The Board of Directors has selected McGrail,  Merkel, Quinn and Associates,
Certified Public  Accountants,  to conduct an independent audit of the financial
statements  of the  Company for the year 2002,  and it is expected  they will be
selected  for the year  2003.  Representatives  of the firm are  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.  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.

     McGrail, Merkel, Quinn and Associates billed the Company and its affiliates
aggregate  fees of $47,000.00  for the audit of the Company's  annual  financial
statements for 2002 and the reviews of the financial  statements included in the
Company's  Forms 10-Q for 2002.  They did not perform any financial  information
systems design or implementation services for the Company in 2002. The aggregate
fees for all other  services  to the Company for 2002  totaled  $27,500.00.  The
Audit Committee has considered whether the services provided by McGrail, Merkel,
Quinn  and  Associates  covered  by the fees  other  than the  audit  fees,  are
compatible with maintaining McGrail,  Merkel, Quinn and Associates' independence
and believes that they are compatible.

Purpose
     The primary purpose of the Audit  Committee (the  "Committee") is to assist
the Board of Directors (the "Board") of Penseco Financial  Services  Corporation
and Penn  Security  Bank and Trust  Company  (collectively,  the  "Company")  in
fulfilling its oversight  responsibilities  regarding reporting of the Company's
financial  information to any  governmental or regulatory  body, the public,  or
other users thereof,  the Company's systems of internal accounting and financial
controls,  legal  compliance  and  compliance  with the  Company's  policies  as
established from time to time by the Board.

Composition
