Thomas Joensen is Co-Managing Partner of the firm's Iowa office. Thomas is a Fellow of the American College of Trial Lawyers — a recognition extended to less than one percent of the nation’s attorneys — who works before and during trial to help clients manage, mitigate and resolve many different types of disputes. While Thomas began his career in medical and legal malpractice, he expanded his experience into litigation involving product liability, employment, all types of professional negligence, board actions, D&O, agricultural, business, debtor-creditor, estate and finance, automobile, and discrimination. He primarily is a member of the Drug & Medical Device practice group but finds great reward in practicing in all of these areas.

Thomas is a formidable first-chair trial attorney. Regardless of the area of law, he takes pleasure in believing his highest and best use is identifying the common sense reasons GRSM’s clients should win while in front of juries, commissions, and various Boards. He has gone to jury trial 18 times as lead counsel. He has also served as lead counsel in five different evidentiary hearings in federal district court. Before the Iowa Supreme Court and Iowa Court of Appeals, he has appeared seven times.

Thomas highly values effective communication, both with GRSM’s clients and when representing them at trial. His background as a speech pathologist also gives him insight into defending clients by communicating ideas in the most straightforward way. He knows the law and the background behind the disciplines, and he skillfully argues clients’ cases.

Thomas enjoys giving presentations to different audiences on a wide range of legal issues — from small groups of clients to large, continuing-education opportunities for colleagues. He also enjoys exercising with his wife and family. He has a special interest in wine from around the world.
