Exhibit 99.1

Mid-Wisconsin Financial Services, Inc. Reports Financial Results for the First
Quarter 2006

April 28, 2006
Medford, Wisconsin

Mid-Wisconsin Financial Services, Inc. (OTCBB:  MWFS.OB), the holding company
of Mid-Wisconsin Bank headquartered in Medford, WI, reported 2006 first quarter
net income of $1.0 million, or $0.61 per diluted share, compared to $1.1
million, or $0.63 per diluted share for the first quarter of 2005.

President & CEO Jim Warsaw reported, "Our financial performance for the first
quarter was negatively impacted by sagging loan demand and a contraction in our
net interest margin.  Seasonal fluctuations in our real estate loan portfolio
combined with a substantial reduction received from a large commercial
borrower, resulted in lower than projected loan balances during the period.
The flat yield curve, coupled with the rising cost of deposits, placed pressure
on our net interest margin, which declined 29 basis points from year end 2005
to 3.79%."

Warsaw continued, "We engaged a third party independent underwriter to evaluate
the level of reserves supporting our self-funded health insurance plan, which
resulted in a one-time expense reversal of $140,000 during the quarter; the net
effect of this adjustment was an increase in net after-tax earnings of $65,000,
or $0.03 per share.  During the first quarter of 2005 we realized a pre-tax
gain of $78,000 from the sale of stock in a cooperative that supported our ATM
network."

Non-interest income for the first quarter was $811,000, an increase of $17,000
over the same period one year ago.

For the quarter ended March 31, 2006, return on average assets (ROA) was .96%
compared to 1.05% for the same period in 2005; return on equity (ROE) for the
first quarter 2006 was 11.32% versus 11.84% for the quarter ended March 31,
2005.

Mr. Warsaw stated, "During the first quarter our Trust & Investment Department
transitioned to a new trade name, Mid-Wisconsin Wealth Management, and
converted to a new retail brokerage platform offered through UVEST.   At March
31, 2006, Mid-Wisconsin's Wealth Management Group reported assets under
management in excess of $205 million. The new retail brokerage platform will
enable us to offer expanded investment options for our customers.  We are
encouraged with the growth of non-interest income from this group which
increased $79,000 over the same period a year ago."

Total assets at March 31, 2006, were $424.5 million compared to $427.4 million
at December 31, 2005.  Total loans grew $4.8 million to $315.5 million and
deposits were up $2.6 million during the first quarter 2006.  "We are expecting
continued growth in loans and deposits when our 13{th} full service branch in
Minocqua opens in July 2006. This branch replaces a smaller, limited-service
branch and will provide greater retail convenience and visibility for this
growing community," remarked Mr. Warsaw.

Asset quality remained strong with nonperforming assets remaining relatively
unchanged at .45% of total assets compared to .35% at December 31, 2005.  Net
loan charge-offs for the quarter equaled .01% of average loans.  Mid-Wisconsin
doubled its provision for loan losses to $125,000 in the first quarter 2006
compared to $62,000 for the same period a year ago.  The allowance for loan
losses increased to .99% of total loans, compared to .97% at year-end 2005.
Mid-Wisconsin believes the balance of the allowance for loan losses at March 31,
2006, is adequate to absorb loan losses inherent in the loan portfolio.  Future
adjustments may be necessary based on growth expectations and changes in
economic conditions.
