Exhibit 99.1

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

July 21, 2006
Medford, Wisconsin

Mid-Wisconsin Financial Services, Inc. (OTCBB:  MWFS.OB), the holding company
of Mid-Wisconsin Bank headquartered in Medford, WI, reported 2006 second
quarter net income of $985,000, or $0.60 per diluted share, compared to $1.1
million, or $0.65 per diluted share for the second quarter of 2005.  Net income
was $2.0 million for the six months ended June 30, 2006 compared to $2.2
million for the same period one year ago.  Jim Warsaw, President & CEO said "As
expected, 2006 earnings continue to be influenced by the costs associated with
the opening of two new full service branches in Rib Mountain and Minocqua and
other expenses related to equipment upgrades, a change in armored car services
and increased utility costs.  In addition, the flat yield curve coupled with
the competitive pricing we've seen for both loans and deposits has placed
increased pressure on our  net interest margin.   Our net interest margin for
the second quarter declined to 3.92% from 4.03% a year earlier.  We see this
condition continuing throughout the remainder of 2006."

Non-interest income for the second quarter of 2006 increased $48,000 compared
to a year earlier.  Investment product commissions have increased due to
increased life insurance commissions and annuity sales.  Mid-Wisconsin rolled
out an overdraft protection program in July 2006 which should result in added
fee income.

Non-interest expense for the three months ended June 30, 2006 increased
$323,000 or 11.5% compared to the same period in 2005.  Personnel and benefit
expense represented approximately $287,000 of the increase due to additional
staffing and normal salary adjustments.
For the quarter ended June 30, 2006, return on average assets (ROA) was .92%
compared to 1.11% for the same period in 2006; return on equity (ROE) for the
second quarter 2006 was 11.24% versus 12.35% for the quarter ended June 30,
2005.

Total Assets were $441.2 million at June 30, 2006 compared to $427.4 million at
December 31, 2005, a 3.2% increase.  Total loans increased $19.0 million to
$329.7 million and total deposits grew $16.6 million during the first six
months of 2006.

Mr. Warsaw indicated that "Commercial loan demand improved during the second
quarter, however, residential mortgage loan activity remains slower than
anticipated. New loan products were introduced during the quarter to generate
consumer interest."

Asset quality remained strong with nonperforming assets relatively unchanged at
..43% of total assets compared to .35% at December 31, 2005.  Net loan charge-
offs for the first six months equaled .02% of average loans.  In anticipation
of future loan growth Mid-Wisconsin continued to support the level of its
allowance for loan & lease losses by providing $250,000 during the first six
months of 2006 compared to $137,000 for the same period in 2005.  The allowance
for loan losses increased to .98% of total loans, compared to .97% at year-end
2005.  The provision for loan losses is determined based on a quarterly process
of evaluating the allowance for loan loss which takes into account various
factors including specific credit allocations for individual loans, historical
loss experience, credit concentrations and changes in portfolio volume.  Mid-
Wisconsin believes the balance of the allowance for loan losses at June 30,
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.
