Dr. Grünheid received his dental degree from the University of Mainz, Germany. After practicing general dentistry for a year, he then completed a three-year orthodontic specialty residency and, upon graduation as a specialist, joined the faculty in the Department of Orthodontics at the University of Mainz. He was on faculty in the Department of Orthodontics at the University of Amsterdam, the Netherlands, before joining the faculty in the Division of Orthodontics at the University of Minnesota.

Dr. Grünheid is committed to excellence and is proud to contribute to education and scientific advancement in the field of orthodontics. He is a published author, has served as a reviewer for several scientific journals, and has lectured nationally and internationally on a variety of topics in orthodontics and oral biology.
