About Benjamin J.
Benjamin J. Heimerl built a steady path from the Midwest classroom to a small-law firm partnership. He earned a B.A. in psychology from the University of Minnesota in 2001. He returned to the state for law school and received his J.D. from Mitchell Hamline School of Law in 2006.
Before becoming a lawyer he served as a sergeant in the United States Marine Corps in 1997. That early service is part of a timeline that moves quickly into law. He began his legal career at Germscheid Law Office, LLC in 2006. A year later he joined Heimerl & Lammers, LLC as a partner, a role he continues to hold.
He was admitted to the Minnesota bar in 2006 and is also admitted to practice before the Federal Circuit. His memberships in professional organizations stretch back to the mid-2000s. He has been a member of the American Bar Association and the Minnesota Association for Justice since 2006. He also joined the Ramsey County Bar Association and maintains membership in the Hennepin County Bar Association. Since 2014 he has served as a barrister in the Douglas K. Amdahl American Inn of Court.
Colleagues describe him as steady in the courtroom and deliberate in preparation. He handles filings and hearings in state court and in federal proceedings when cases require it. His practice reflects a courtroom orientation born of trial and appellate work rather than transactional law.
Heimerl’s background combines military service, early entry into private practice, and sustained involvement in local and national bar groups. That mix informs how he approaches cases: methodical preparation, attention to procedural detail, and a readiness to argue on behalf of clients when matters proceed to trial or appeal.
At Heimerl & Lammers, LLC he shares responsibility for client intake, case strategy and courtroom advocacy. He maintains active memberships in several legal associations and continues to participate in the Douglas K. Amdahl American Inn of Court as a barrister. He practices in Minnesota state courts and in federal matters before the Federal Circuit.
