Item  4.    Changes  in  Registrant's  Certifying  Accountant.

     On  April  24,  2003, Celerity Systems, Inc., (the "Company") notified HJ &
Associates,  ("HJ")  that  the Company has dismissed HJ as its auditor. On April
25,  2003, the Company engaged Marcum & Kliegman, LLP as independent auditors of
the  Company  for the fiscal year ending December 31, 2003. The action to engage
Marcum  &  Kliegman,  LLP  was  taken  upon  the unanimous approval of the Audit
Committee  of  the  Board  of  Directors  of  the  Company.

     During  the  last two fiscal years ended December 31, 2002 and December 31,
2001  and  through  April  24, 2003, (i) there were no disagreements between the
Company  and  HJ  on any matter of accounting principles or practices, financial
statement  disclosure  or  auditing scope or procedure which, if not resolved to
the  satisfaction  of HJ would have caused HJ to make reference to the matter in
its reports on the Company's financial statements, and (ii) HJ's reports did not
contain  an  adverse  opinion  or  a  disclaimer of opinion, or was qualified or
modified  as  to  uncertainty, audit scope, or accounting principles. During the
last  two most recent fiscal years ended December 31, 2002 and December 31, 2001
and  through  April  24,  2003,  there  were  no  reportable  events as the term
described  in  Item 304(a)(1)(iv) of Regulation S-B. HJ 's opinion in its report
on  the  Company's financial statements for the year ended December 31, 2002 and
2010,  expressed  substantial  doubt  with  respect  to the Company's ability to
continue  as  a  going  concern.

     During  the  two  most  recent fiscal years and through April 24, 2003, the
Company  has  not  consulted  with  Marcum  &  Kliegman,  LLP  regarding either:

     (a)  the application of accounting principles to any specified transaction,
either  completed  or  proposed,  or  the  type  of  audit opinion that might be
rendered on the Company's financial statements, and neither a written report was
provided to the Company nor oral advice was provided that Marcum & Kliegman, LLP
concluded  was  an  important  factor  considered  by  the Company in reaching a
decision  as  to  the  accounting,  auditing  or  financial  reporting issue; or

     (b) any matter that was either subject of disagreement or event, as defined
in  Item  304(a)(1)(iv)(A) of Regulation S-B and the related instruction to Item
304  of Regulation S-B, or a reportable event, as that term is explained in Item
304(a)(1)(iv)(A)  of  Regulation  S-B.

     The Company has requested that HJ furnish it with a letter addressed to the
Securities  and  Exchange  Commission  stating  whether it agrees with the above
statements.  A  copy  of  such letter, dated April 28, 2003, is filed as Exhibit
99.1  to  this  Form  8-K.

undersigned  hereunto  duly  authorized.
