"I’m one lucky guy.  I have a wonderful wife and family.  I love numbers and am passionate about helping people.  During the day (I hesitate to call it “work” or a “job”), I get the opportunity to collaborate with my son and partner Brett and our DWM teammates and other professionals to add value to the lives of friends.  Priceless.”

Les Detterbeck was born in Chicago, a few blocks from Wrigley Field and is a die-hard, World Series Champion, Cub fan.  In 1976, he started Detterbeck, Johnson & Monsen, a Palatine, IL accounting and tax firm, and continues today as its Chairman of the Board. Les has been active in many charities in Chicago and Charleston. Les married his college sweetheart, Elise, in 1969.
