Dr. Roger Moynihan DDS & Dr. Amy Jessel DDS 

Dr. Roger P. Moynihan and Dr. Amy B. Jessel


Dr. Roger Moynihan was born and raised in Holyoke, MA.  He graduated from the College of the Holy Cross in 1979 with a B.A. in Chemistry.  He then attended Northwestern University Dental School, and graduated in 1983.  After dental school, he completed a General Practice Residency at Waterbury Hospital in Waterbury, CT.

Dr. Amy Jessel was raised in Palos Verdes, CA and graduated from the University of California,  Davis with a B.S. in Zoology in 1979.  She also attended Northwestern University Dental School and graduated in 1983.  After dental school, she completed a General Practice Residency at the V.A. Hospital in La Jolla, CA.

In 1985  the doctors were married, and each spent four years working as associate dentists in the Los Angeles area. Their dream was to one day work together and to establish a practice which would serve the community with excellent dentistry from caring, family-friendly professionals that put the patient first. In 1988, they moved to northern San Diego county, and opened Mission Family Dentistry in Oceanside.

The doctors are past and present members of the American Dental Association, California Dental Association, San Diego County Dental Society, Chicago Dental Society, Academy of General Dentistry, Seattle Study Club, North County Networking, and the Oceanside Chamber of Commerce. When not practicing dentistry, they are both involved in several community service organizations. Dr. Moynihan was  a volunteer with Project Wildlife’s raptor team for 16 years, and is currently a responder for CERT and a member of the Fallbrook Amateur Ham Radio Club.  Dr. Jessel volunteers her time doing  philanthropic work and enjoys interior decorating.  Their daughter, Katie, is a dental hygienist.  She and her husband, Dylan,  live in Gilbert, AZ.   Their son, Rob, works in the television industry in Los Angeles. He and his wife, Jenn,  are new parents to the doctor's first grandchild, Sutton Marie!

Our office manager, Tricia, has been a part of our team since 1995.

Whether you need to schedule an appointment, or have insurance or billing concerns, she is always ready to assist you with any questions that you may have.  Tricia enjoys spending time with her adult twin sons and granddaughter.  She loves reading and cooking.

 Martha and Bonnie are our Registered Dental Hygienists. They not only perform gentle and thorough cleanings, but they are also experts in the field of periodontal disease. Since it is the goal of our practice to practice prevention, they help our patients maintain the health of their teeth and gums. They are also both certified to provide Vizilite examinations to screen our patients for oral cancer.

Debbie and Massooda are our chairside Registered Dental Assistants.  They have many years of assisting experience, and both are trained in Zoom! bleaching.  Each of them assist both doctors with all of our patient's dental procedures, and they are dedicated to making your dental appointment a relaxing, enjoyable one.
