Ken has worked with Fehr Graham clients for more than three decades, joining the firm in 1989 and becoming an owner in 2002. You could say compliance is his middle name because Ken is frequently called upon by industrial and manufacturing clients to ensure they stay environmentally compliant.

Ken takes Fehr Graham’s core values to heart by mentoring younger staff members and driving the firm's strategic plan, helping Fehr Graham successfully grow to 10 offices in three states. Ken also helps the communities in which the firm works by giving back of his time and talent. He is a part of the Board of Directors for State Bank in Freeport, Illinois, and is a member of several environmental associations.

He holds a bachelor's degree in Industrial Technology Education from the University of Wisconsin-Platteville. Ken and his wife, Marcia, live in Freeport and have two adult children.
