James B. Barton is an attorney based in Milwaukee, WISCONSIN. The practice focuses on Business and Litigation. James has over 18 years of legal experience. Currently practicing at Barton Cerjak SC. James works from Milwaukee, Wisconsin and takes on business matters across the region.

James Barton is the founding shareholder of Barton Legal S.C. Mr. Barton was formerly a partner at Hansen Reynolds LLC—a premier litigation boutique with offices in three states. Prior to his time at Hansen Reynolds, Mr. Barton was an associate in the litigation practice group at Michael Best & Friedrich LLP, one of Wisconsin’s oldest and largest law firms.

Mr. Barton concentrates his practice on aggressively litigating complex commercial disputes venued in state and federal courts across the country. Although litigation remains his primary focus, the skills Mr. Barton has developed by litigating high-stakes cases throughout the country allow him to service his clients in a broader role—as a problem-solver who is just as comfortable resolving a matter in the boardroom as he is in the courtroom.

Regardless of how or where a dispute arises, Mr. Barton’s approach to each matter remains the same: what constitutes a “win,” what is needed to achieve that win, and what will it cost to make that vision a reality? This type of common-sense lawyering has earned Mr. Barton the trust and respect of his clients; not only as a litigator, but as a trusted advisor who his clients rely on to offer prudent advice and pragmatic solutions to the myriad issues affecting their businesses.
