5 /5 Pam Karlson: Dr. Guelff has been treating my family members for 20 years! My husband has TMJ and wears a bruxing guard that Dr. G built and maintains for him. Dr. G has also handled all of the orthodontic needs of both of our children. He has been a major positive influence in our sons life as well. Dr. G is active in our community and continuously gives back. We love Dr. G and would recommend him and his staff to both adults and children who have orthodontic needs. Moms seal of approval!
