About me

Visit my website at I received my undergraduate degree from Marquette University in 2005 with a triple major in English Composition, Philosophy, and Comparative Theology. I received enrolled at Marquette University Law School in 2007 and received my law degree in 2010.


I focused my legal education on Estate Planning, Dispute Resolution, Mediation, and Restorative Justice. While at Marquette, I founded and served as the President for the Restorative Justice Society and served on the boards of the Alternative Dispute Resolution Society and the Client Skills Board. I was inducted into the Pro Bono Society with high honors for outstanding volunteer involvement with the Volunteer Income Tax Assistance Program and the Milwaukee Foreclosure Mediation Program. I also mediated small claims disputes for the Milwaukee County Circuit Court.


My practice has focused on Family Law, Estate Planning, and Probate, helping clients of all asset levels navigate through Will and Trust challenges, custody and placement disputes, legal separation, and divorce. As much as possible, I help my clients avoid conflicts through comprehensive estate planning, probate-avoidance techniques, powers of attorney, and pre- and post-nuptial agreements. My goal is to limit emotionally draining and expensive legal battles while assuring that my clients' interests are protected.
