               CERTIFICATION PURSUANT TO RULE 13A-14(A)/15D-14(A)

     I, James F. Warsaw, certify that:

     1. I have reviewed this Annual Report on Form 10-K of Mid-Wisconsin
Financial Services, Inc. (the "registrant");

     2. Based on my knowledge, this 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 report;

     3. Based on my knowledge, the financial statements, and other financial
information included in this 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 report;

     4. The registrant's other certifying officer(s) 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)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(e)) for the
registrant and we 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 report is being
     prepared;

        (b) designed such internal control over financial reporting, or caused
     such internal control over financial reporting to be designed under our
     supervision, to provide reasonable assurance regarding the reliability of
     financial reporting and the preparation of the financial statements for
     external reporting purposes in accordance with generally accepted
     accounting principles;

        (c) 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

        (d) disclosed in this report any change in the registrant's internal
     control over financial reporting that occurred during the registrant's
     fourth 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 officer(s) and I have disclosed, based
on our most recent evaluation of internal control over financial reporting, 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.
