Gary A. Groff  D.D.S., M.A.G.D.

Dr. Groff has been a dentist in Clinton for 32 years, setting up his practice here after graduating from UMKC School of Dentistry in 1984.  Dr. Groff is a member of the American Dental Association, the American Academy of Cosmetic Dentistry, and has earned a Mastership  from the Academy of General Dentistry.  He is a member of the Greater Kansas City Dental Society and the Pankey Study Club, having served the latter as a past-president. He participates in the "Give Kids a Smile" program, in addition to donating time with the "Mission of Mercy" projects in Kansas and Missouri. 

Because of his passion for his patients’ care and the art of dentistry, Dr. Groff has earned over 2,000 hours of continuing education in nearly every area of dentistry.  He believes that his patients deserve the finest oral care possible, since this contributes immensely to their personal health and well-being.  He is also very mindful to provide comfort and alleviate any concerns or problems his patients may bring to the practice.

Dr. Groff grew up in Clinton, graduated from Clinton High School, and enjoys being a part of this community.  He is a member of the Truman Lake Community Foundation, has donated many hours to the Henry County Health Center Dental Clinic, and is a board member and supervising dentist at State Fair Community College’s Dental Hygiene program. He has been very dedicated to Clinton’s Boy Scout organization, and has enjoyed participating in outdoor activities, such as the deer hunter’s breakfast, campouts, float trips, and, of course, Philmont!  Dr. Groff has fun playing his trumpet with Clinton’s Community Band, the First Baptist Church band, the Warrensburg Community Band, and has been known to play at the Clinton United Methodist Church band, too. 

Dr. Groff takes great pleasure in getting to know his patients, and would love to welcome you into our patient family!
