Patient Care

Dr. Gruenheid practices full scope orthodontics in the University of Minnesota Orthodontic Faculty Practice. The Faculty Practice is a specialty clinic staffed by current School of Dentistry faculty and operates like orthodontic offices outside the School of Dentistry. Dr. Gruenheid has served as the Director of the Orthodontic Faculty Practice since 2012.
