About me

After being raised on a Southwest Wisconsin farm, Mark met his wife, Ann Zwicky, a Sturgeon Bay native, during college and chose to establish in Northeastern Wisconsin.  Mark and Ann have two children, David and Michael, each who have internatonal families that has expanded Mark's interests worldwide.  "One of the best things about Wisconsin is the community of friends and clients.  I love life here. Give back to the community you love."

Mark's dedication is evident not only in his work but also in his community, including the Door County Community Foundation, Inc., Rotary Club of Sturgeon Bay and many other organizations.  He is currently or has been on the boards of the State Bar of Wisconsin Section Leaders, General Practice, Law Office Management, and Tax Sections, Door County and Door-Kewaunee County Bar Associations, Door County Community Foundation, Birch Creek Music Performance Center, Door County Maritime Museum, Door County Chamber of Commerce (now the Door County Visitor and Convention Bureau), Sturgeon Bay Community Development Corporation (now the Sturgeon Bay Visitor and convention Bureau), Boy Scout Leader (Cub Master), Hope United Church of Christ Council and Boards, Magic Years Preschool Board (now Treehouse Learning Center), Door County Community Child Care Center, HELP of Door County, University of Wisconsin Alumni Club of Door County, and others.
