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.
