Louie Lange III

Principal, Founder

Office:  Fond du Lac, WI

Focus: Continuing to grow the firm that started in his basement, to a team in excess of 300 people and $100 million in annual revenue. Louie has a keen eye for maximizing revenue opportunities from every opportunity in the development, construction and property management of real estate. Many times, this desire has led to horizontal and vertical integration of Commonwealth’s business through partnerships, acquisitions and the “start-up” of new ventures. More recently, shifted his main leadership focus to capitalize on opportunities and strengths within Commonwealth Construction Corporation.

Commonwealth was quick to respond to any need, both large and small, throughout the entire building process. It might sound too good to be true, but all we did was tell them what we wanted and they did it. Very simple and no surprises. It is easy to see why Commonwealth is a rapidly growing company.
