About me

I am a business and employment law attorney focusing on the business, employment and litigation needs of entrepreneurs and growing businesses. I frequently advise clients on mergers & acquisitions, employment agreements, non compete and severance agreements, and trademark and copyright disputes.

My transactional background, coupled with my understanding of and experience in pursuing litigation when necessary, is particularly well-suited to small and medium-sized businesses that need their legal concerns addressed promptly, efficiently, and effectively. 

I pride myself on exceeding my clients’ expectations. My responsiveness, creativity and ability to efficiently evaluate, advise and advocate for clients has earned me the respect of peers, as I have been named a Rising Star multiple times by Minnesota Law & Politics magazine. 

I graduated from the University of Minnesota Law School in 1997, where I was a managing editor for the Minnesota Law Review. After graduating from the University of Minnesota, I joined the Hinshaw & Culbertson law firm in its Minneapolis office, practicing primarily in business and corporate law. I am a founding partner of Trepanier & MacGillis P.A., which added a shareholder in 2013 and is now known as Trepanier MacGillis Battina P.A.

I have spoken before classes at the University of St. Thomas New Venture MBA Program. I am currently co-chairman of the Lawyer Referral & Information Service of the Hennepin County Bar Association, and am a former member of the Board of Directors of Americoach, a Twin Cities-based nonprofit. 

I regularly volunteer with the Hennepin County Self-Help Expungement Clinic, and assist low income clients through the Volunteer Lawyers Network.

  • Joseph Francis Henderson

    I have known Jim since we were classmates in law school and have always considered him to be at the top of his class in skill, passion, communication abilities, and the ability to go well beyond the ordinary to understand his clients' needs and fight on their behalf. I've referred clients to Jim over the years and hear nothing but great feedback. On top of his strong reputation in the community and excellent legal skills, Jim happens to be an extremely nice and likable guy with strong integrity. I strongly endorse him.
