Dr. Less was born and raised in Toledo, Ohio. He graduated from The Ohio State University College of Dentistry in 1974, and is a veteran of the Air Force Dental Corps. Starting in 1978, Dr. Less spent the next 20 years in his Ohio general dental practice dedicated to pain management and full mouth reconstruction. In 1997 Dr. Less returned to school at the University of Southern California Dental School where he obtained a Certificate of Endodontics from the school’s Endodontic Residency Program. He opened his practice in Turlock on October 1, 1999. Dr. Less is passionate about endodontics, and with his background as a general dentist, he brings a unique perspective to the practice of this area of dentistry. Dr. Less is a member of the American Dental Association, the California Dental Association, and the American Association of Endodontists.  

There are numerous interests in Dr. Less’ life, but family, following Ohio State football, travel, working out, and reading occupy most of his spare time.

Lisa has been Dr. Less’s lead assitant since 1999 and an endodontic RDA since 1996. She is very detail-oriented and now is Turlock Endo's Office Manager. She enjoys spending time with her family and scrapbooking. Lisa is bilingual in Portuguese.
