Judicial Experience

John served on the bench as a full-time judicial court commissioner from 1991-1993. He heard and decided hundreds of legal matters and wrote extensive judicial opinions on complex issues and cases.  He conducted bail hearings, small claims mediations, mental health commitments, and guardianships, among other actions.  He made national news for setting record high bail on a defendant charged with stunning animal abuses. Of John’s judicial service, Wisconsin Supreme Court Justice Ann Walsh Bradley wrote: "John's dedication shows. He meets the challenges with quality. He has keen insight into developing legal issues."

Estate Planning Private Practice

After earning his Juris Doctor from the University of Wisconsin Law School in 1991, John began private law practice in Madison, Wisconsin in 1993, writing several major appeals, two of which were ordered by the Wisconsin Court of Appeals to be published, an honor reserved only for cases that are deemed significant in their effects on Wisconsin law.

Estate Planning Expertise

Since 1998, John has dedicated his legal practice to all aspects of estate planning, including Medicaid planning and Medicaid planning trusts, will-based planning, probate, guardianship, and trust administration. He has also performed as a probate attorney and guardian attorney. His clients range from business owners in need of basic estate planning services to high net worth individuals requiring advanced estate planning techniques. John takes great pride knowing that the service he performs provides peace of mind to his valued clients and their families.

John also believes very strongly in giving back to the community that has supported him for so many years. He enjoys performing charitable and pro bono work, often working weekends with elderly low-income Wisconsinites needing legal and estate planning basics at no charge. He has also provided pro bono services to eligible first responders and their spouses or domestic partners through the State Bar of Wisconsin’s Wills for Heroes program, volunteering to help prepare wills and other estate planning documents at no charge to these heroes and their families.
