Thank you for your support of MTHS.   With your help, the Mequon Thiensville Historical Society has grown to include over 200 voting members.  Major contributors have included Sommer's Motors, Van and Susan Mobley, The Mequon Community Foundation, former Mequon Mayor Connie Pukaite, and the Mequon-Thiensville Sunrise Rotary Club.  More recent benefactors include the Cedarburg Auction Company and Anderson Painting.  We are a 501(c)(3) non-profit organization, and all donations, including membership dues, are fully tax deductible.  

Mark your calendars for Sunday, November 9th, 2014, when we are sponsoring a presentation by Tom Nieman.  Tom and his family have managed several major business in southern Ozaukee County during the past 100+ years.  The presentation will be at 2 PM at the City of Mequon council chambers on Cedarburg Road.  This program is free and open to the public, and will be preceded by our MTHS Annual Meeting at 1:30 PM.
