Mark S. Knutson is a native of New Berlin, WI. He graduated from Catholic Memorial High School in 1971 and went on to St. Mary’s University in Winona, Minnesota, graduating in 1975. While there, he met his wife Patti. Upon graduation she took a job at KPMG as an Accountant in Chicago, and Mark attended Loyola University Law School. He graduated from Loyola in 1978.

Longing to return to Wisconsin after finishing law school, he took and passed the Wisconsin bar exam, then began working with the Hartman Law Office in Juneau, Wisconsin that year. Eventually he and Patti and their two children, Kristin and Katie, made their home in Brookfield, WI, where Mark started his own law firm in 1994, The Law Offices of Mark S. Knutson, S.C. His practice began with Family Law, Wills and Estates, and Traffic matters. As time went on, attorneys were hired to focus on Estate Planning, Probate and Civil Litigation. Divorce and Family Law continue to be Mark’s primary areas of focus to this day.

Mark and Patti have been members of Elmbrook Church for over 30 years. He loves the outdoors and gardening. He enjoys spending time with his friends at the Waukesha Gun Club and students through his involvement with the high school ministry at Elmbrook Church.

What our clients say about Mark

"Making the decision to file for divorce was the most difficult decision I've ever had to make. It was truly a blessing to me to be able to work with such compassionate and caring people. Mark made sure that I felt very secure in knowing that he was there to protect me. I was very nervous about the entire process, and I had no idea what to expect. He made sure that I understood everything that was taking place by walking me through it, step by step. I trusted him completely, and I would recommend his services to anyone who would be in need of a trustworthy, respectable and caring attorney."

Laura O.

During the past year, I have tried numerous cases against some of the top trial attorneys, but I'll take this opportunity to inform you that none of them shared your abilities...Also, I hope you won't mind, but I've passed this along to your client and although I doubt he needs a second opinion on the topic, he deserves to know that he hired a top-flight attorney."

Lord bless each of you."
