Doctorate of Dental Surgery: University of Minnesota School of Dentistry, Minneapolis, 2010

Dr. Anderson grew up in Eau Claire, WI and later went on to receive his Bachelor of Arts in 2001 from Gustavus Adolphus College in St. Peter, MN.  With a career in dentistry always in mind, he spent a number of years working as a wild land firefighter.  This work reinforced his interest in working with his hands, but lacked the kind of personal interaction he wanted in a long term career.  In 2006 he enrolled at the University of MN and earned his Doctorate of Dental Surgery from the U of M School of Dentistry in 2010.  While in dental school, he volunteered weekly at the Union Gospel Mission free dental clinic and helped coordinate Give Kids a Smile activities on campus.  After graduation he completed a General Practice Residency and a Fellowship in TMJ/Orofacial Pain at Hennepin County Medical Center (HCMC) in Minneapolis.  Dr. Anderson enjoys the challenges and variety of work that dentistry offers, and greatly values building relationships with his patients.
