Exhibit 99.1

Mid-Wisconsin Financial Services, Inc. Reports Financial Results for the Fourth
Quarter and Year-End 2006 Results

January 29, 2007
Medford, Wisconsin

Mid-Wisconsin Financial Services, Inc. (OTCBB:  MWFS.OB), the holding company
of Mid-Wisconsin Bank headquartered in Medford, WI, reported a 2006 fourth
quarter net loss of $1.8 million, or ($1.11) per diluted share, compared to net
income of $1.1 million, or $0.62 per diluted share for the fourth quarter of
2005.  As reported on Form 8-K filed January 22, 2007, the 2006 results were
negatively impacted by the recording on a specific loan loss provision of $4.6
million or $2.75 million on an after-tax basis related to loans made by its
principal subsidiary, Mid-Wisconsin Bank ("Bank"), to a business entity and its
owners. The effect of providing the additional loan loss expense was a
reduction of $1.67 per share on a diluted basis. Excluding the impact of the
additional provision for loan losses, net income would have been $.9 million or
$.56 per share for the fourth quarter of 2006.

Net income for the year ended December 31, 2006 was $1.1 million or $.66 per
diluted share as compared to $4.4 million or $2.57 per fully diluted share in
2005.  Return on average assets (ROA) for 2006 was .25% compared to 1.06% in
2005. Return on equity (ROE) for 2006 was 3.07% versus 12.04% in 2005.

Nonperforming assets at year end 2006 include $5.1 million in loans to the
impaired borrower described above. The potential repurchase of certain loan
participations related to this relationship is also included in the additional
provision of $4.6 million. Excluding this additional specific provision, the
allowance for loan losses was $3.6 million or 1.02% of year-end loans. The Bank
has performed additional work in the loan areas as well as retained outside
consultants to evaluate the accuracy of risk grades assigned to the credits
reviewed, complete financial and documentation checklists, and provide feedback
on the observed credit administration practices. Based on the internal and
external reviews performed, we believe that the allowance for loan losses is
adequate as of December 31, 2006.

Mid-Wisconsin Financial Services, Inc., headquartered in Medford, Wisconsin, is
the holding company of Mid-Wisconsin Bank which operates thirteen retail
banking locations throughout central and northern Wisconsin serving markets in
Clark, Eau Claire, Lincoln, Marathon, Oneida, Price and Taylor counties. A new
branch in Eagle River is expected to open in April.  In addition to traditional
loan and deposit products, the Bank offers trust, discount and full-service
brokerage services, insurance services through its subsidiary Mid-Wisconsin
Wealth Management and also performs residential real estate appraisals and
title insurance services through a corporate subsidiary, Excel Real Estate
Services, Inc.
