What We Do


We are a volunteer-driven educational and research non-profit.

Mequon-Thiensville Historical Society (MTHS) provides resources and educational services to the citizens of Mequon and Thiensville in an effort to inspire an appreciation for our rich local history. We achieve this through the preservation of archives as well as adult and childhood history education programs and events.
