Meet Us

Meet Our Northern Michigan Defense Lawyers

Defense Attorneys Mas/Stig-Nielsen is a 100% family owned and operated business. We met and married while attending Lewis & Clark Law School in Portland, Oregon. Since 2013 we have lived and worked in Benzie County. We have a wonderful daughter, Francisca, and are expecting our second child, a boy, in late summer of 2021.

Mary Elizabeth (Betsy) Mas

Betsy’s passion is the outdoors. She is happiest when she is running, hiking, biking or sitting in the sunshine. She considers herself incredibly lucky to live and work in such a beautiful location. She and Frederik have traveled the world and will continue to do so with two kids in tow.



Frederik Stig-Nielsen

Frederik’s ancestors were Vikings. He spends his free time adventuring with his family and cooking in the wild. Frederik is an unaccomplished sawyer and whether indoors or out, he spends countless hours learning B.B. King, Duane Allman, and Carlos Santana licks on his American-made guitars.
