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.

Mr. MacGillis and his law firm provided me with excellent legal assistance. He was prompt with communications, both with answering my questions, and keeping me up to date on the progression of our case. He included me in all decisions, and made it a very simple process for me. His knowledge, and the contributions from the staff at Trepanier and MacGillis, were directly responsible for the positive result I was seeking.
