Since its founding in 1979, the dental facility has been dedicated to providing quality dental healthcare to its patients. Their commitment to reasonable pricing, Ozark hospitality, and unique same-day service is how Doctors Harold E. George and Frederick C. Lauer made Mid-America Denture Clinic so special. Dr. Jay Hildreth continued that legacy when he established the Dental Centers' practice in 1995 and purchased the Mid-America Denture Clinic in 1997.

Their son, Scott George, is a Board-certified Hearing Instrument Specialist and President for all non-professional services.
