About Mr. John O.
Mr. John O. Knappmann earned his J.D. from the University of Michigan Law School in 1989. He moved into practice in Michigan after graduation and has built a career rooted in the state's trial and transactional courts. His legal education at Michigan set the foundation for a practice that touches both criminal and property law.
Knappmann’s professional life is organized around active participation in local and state bar groups. He serves as Vice-President of the Downriver Bar Association and maintains membership in the Michigan Association of OWI Lawyers, the Criminal Defense Lawyers of Michigan, and the Wayne County Criminal Bar Association. He also belongs to the Michigan State Bar Real Property Section and the Michigan Bar Probate Section. Outside the bar, he is involved with the Wayne County Real Estate Investors Association and the Brownstown-Woodhaven Rotary Club.
Those memberships reflect the two main strands of his work: criminal defense and real property matters. He has represented clients on charges ranging from OWI to other criminal offenses, and his affiliation with several criminal defense organizations signals an ongoing engagement with contemporary criminal practice and procedure in Michigan. On the property side, his involvement in real estate investor groups and the state bar’s real property section suggests regular work on transactions, title issues, and related civil matters.
Colleagues describe him as steady and straightforward in court. He appears before county and municipal courts and works on cases that require both courtroom advocacy and negotiation skills. His practice also touches probate issues, informed by membership in the state bar’s probate section, which keeps him connected to developments affecting estates and succession matters.
Knappmann combines bar activity, local civic participation, and hands-on legal work. He keeps current by participating in professional organizations and community groups that overlap with his areas of practice. He currently practices in Michigan, handling criminal defense, OWI, real property, and probate matters.
