                      NUTRITION MANAGEMENT SERVICES COMPANY

                           A PENNSYLVANIA CORPORATION
                  CERTIFICATION OF PRINCIPAL EXECUTIVE OFFICER

                            Section 302 Certification

I, Joseph Roberts, certify that:

     1.  I have  reviewed  this  quarterly  report  on Form  10-Q  of  Nutrition
         Management Services Company, Inc.;

     2.  Based on my  knowledge,  this  quarterly  report  does not  contain any
         untrue  statement of a material  fact or omit to state a material  fact
         necessary to make the  statements  made, in light of the  circumstances
         under which such  statements  were made, not misleading with respect to
         the period covered by this quarterly report;

     3.  Based on my knowledge,  the financial  statements,  and other financial
         information  included in this quarterly  report,  fairly present in all
         material  respects the financial  condition,  results of operations and
         cash flows of the  registrant as of, and for, the periods  presented in
         this quarterly report;

4.       The registrant's  other  certifying  officers and I are responsible for
         establishing  and  maintaining  disclosure  controls and procedures (as
         defined  in  Exchange  Act  Rules  13a-15(e)  and  15d-15(e))  for  the
         registrant and have:

         a)    designed such disclosure controls and procedures,  or caused such
               disclosure  controls  and  procedures  to be  designed  under our
               supervision, to ensure that material  information relating to the
               registrant,  including  its  consolidated  subsidiaries,  is made
               known to us by others within those entities,  particularly during
               the period in which this quarterly report is being prepared;

         b)    evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls  and   procedures  and  presented  in  this  report  our
               conclusions  about the  effectiveness of the disclosure  controls
               and  procedures,  as of the  end of the  period  covered  by this
               report based on such evaluation; and

         c)    disclosed in this report any change in the registrant's  internal
               control  over  financial   reporting  that  occurred  during  the
               registrant's  most  recent  fiscal  quarter  that has  materially
               affected,  or is  reasonably  likely to  materially  affect,  the
               registrant's internal control over financial reporting; and

5.       The registrant's other certifying officers and I have disclosed,  based
         on our most recent  evaluation,  to the  registrant's  auditors and the
         audit  committee  of  registrant's   board  of  directors  (or  persons
         performing the equivalent functions):

         a)    all  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal control over financial  reporting
               which are reasonably  likely to adversely affect the registrant's
               ability  to  record,  process,  summarize  and  report  financial
               information; and

         b)    any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
               internal control over financial reporting.
