Dr. Trey

Dr. Amon “Trey” Holt

Like most aspiring dentists from Arkansas, he had planned to attend the University of Tennessee-Memphis School of Dentistry and was accepted there during his senior year of college. However, after travelling to Kansas City for the first time to visit family, he fell in love with the area and knew that Kansas City was somewhere he could call home.

He then completed a two-and-a-half-year residency in Periodontics at UMKC before entering private practice. He is a Diplomate of the American Board of Periodontology and has been a member of multiple organizations including the American Dental Association, the Kansas Dental Association, the Mo-Kan Society of Periodontics, and the American Academy of Periodontology.
