ITEM 4.01   CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.
            ---------------------------------------------

      (a)   McGladrey & Pullen, LLP was previously the principal accountants for
            SI Financial Group, Inc. (the "Company"). On March 15, 2005, the
            Company dismissed McGladrey & Pullen. The decision to change
            accountants was approved by the Company's Audit Committee. In
            connection with the audits of the two fiscal years ended December
            31, 2004 and the subsequent interim period through the date of
            dismissal, there were no disagreements with McGladrey & Pullen on
            any matter of accounting principles or practices, financial
            statement disclosure, or auditing scope of procedure, which
            disagreements if not resolved to their satisfaction would have
            caused them to make reference to the subject matters of the
            disagreements in connection with their report. In addition,
            McGladrey & Pullen's reports on the Company's financial statements
            for the two fiscal years ended December 31, 2004 contained no
            adverse opinion or a disclaimer of opinion, and were not qualified
            or modified as to uncertainty, audit scope, or accounting
            principles.

            The Company requested that McGladrey & Pullen furnish the Company
            with a letter, as promptly as possible, addressed to the Securities
            and Exchange Commission, stating whether it agrees with the
            statements made in response to Item 304(a) of Securities and
            Exchange Commission Regulation S-K in this Item 4.01, and if not,
            stating the respects in which they do not agree. That letter is
            filed as Exhibit 16.1 to this Report.

      (b)   On March 15, 2005, the Company engaged Wolf & Company, P.C. as the
            Company's principal accountants. For the two fiscal years ended
            December 31, 2004 and up to the date of the dismissal of McGladrey &
            Pullen, the Company did not consult Wolf & Company regarding either:
            (1) the application of accounting principles to a specified
            transaction, either completed or proposed; (2) the type of audit
            opinion that might be rendered on the Company's financial
            statements; or (3) any matter that was either the subject of a
            disagreement with McGladrey & Pullen on any matter of accounting
            principles or practices, financial statement disclosure or auditing
            scope or procedure or the subject of a reportable event.

                              Item 4.01(a)
