William David Block

About me

My practice focuses on family law, estate planning, and probate, helping clients navigate through will and trust challenges, custody and placement disputes, legal separation, and divorce.  As much as possible, I help my clients and their families avoid conflicts through comprehensive estate planning, probate-avoidance techniques, powers of attorney, and pre- and post-nuptial agreements. I believe that preventative measures are always better than trying to fix a problem after it happens.  That's not always possible, though.  For situations where a conflict cannot be avoided, my approach is to limit emotionally draining and expensive legal battles to the extent possible while still fighting for you to make sure your interests are protected. 

Before opening my own practice, I worked at several other firms, including a small family-owned office, a medium-sized multi-attorney general practice firm, and high-end firm on the top floor of an office building in downtown Milwaukee.  I learned a lot from each of these experiences and was motivated by the successes of those I worked with to venture out and design a business that matched my own vision.  

I received my law degree from Marquette University Law School 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 of the Restorative Justice Society. I also served on the boards of the Alternate 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 at the Milwaukee County Circuit Court. 

I received my undergraduate degree from Marquette University in 2005 with a triple major in English Composition, Philosophy, and Comparative Theology. I live in Wauwatosa with my wife and three children.
