My Background

Douglas A. Treyz DMD

I’ve been a trusted, practicing medical professional for the Westchester community since 1988. I understand that your health and wellness concerns extend beyond routine medical care. I’m a highly trained, board-certified Dentist and provide an array of comprehensive services and procedures within my field. 

My academic career started at Fairleigh Dickinson Dental School in 1984.

I began practicing dentistry in May of 1988 , then moved to the Katonah Medical Group with my father, sister and brother in law. I practiced in that medical group for 8 years then branched out into my own private practice in 1996 until present.


I am a member of the American Dental Association as well as the New York State Dental Association and Foundation. I continue my education by regularly attending conferences as well as belonging to the Westchester Endodontic study club,  and Lazers and Dentistry study club. 

I have lived in the Katonah-Lewisboro community for over 50 years; and have raised y 4 children here, 2 of which are in Dental School.  My goal is to provide a trusting, relaxed experience for all of my patients.
