Jennifer began her dental career in 1988 as a Registered Dental Assistant. She transferred to the front office in 1996 but still has the knowledge and abilities to work hands on with the patients in the back-office treatment rooms. Jennifer has decades of expert knowledge in working with dental insurance companies to be sure our patients get the maximum benefits within their policies. She has worked for Dr. Duffin since 2015 and absolutely thinks he is BY FAR the best dentist she's ever worked for.

Jennifer resides on a Temecula ranch now with her new husband, running a couple Airbnb’s, but she grew up in Rancho Cucamonga. She has two young adult daughters: one of which is a school teacher for Fallbrook School District. Taking her daughters lead, Jennifer returned to college and recently earned a degree in Business Administration.


Sonia D.

Sonia’s dental career started after graduating Register Dental Assisting School in 2006. She has worked for Dr. Duffin since 2012. Sonia enjoys working side by side with Dr. Duffin each day. She feels blessed to work with a dentist that truly cares about his patients. Helping patients feel welcome and comfortable is very important to her as well. Sonia loves to interact with and educate her patients with her dental knowledge.

Sonia loves to go hiking, traveling all over, reading, and having her toes in the sand at the beach. When she is not busy, she enjoys time with family and friends. Sonia has one daughter who recently joined the health care industry as well.



Sandra’s first careers involved illustrating educational films and materials for college nursing courses; then later designing instructional materials, packaging, logos, and marketing programs for a medical products company. When she received a job offer closer to home, from an area newspaper Advertising Director, she accepted, and made the leap into what would become a wonderful 20+ year adventure into advertising sales and management. There she learned that customer service was king. As the newspaper industry continued to downsize, closing the majority of offices, she went back to college; earned certifications in Medical Billing and Coding; as well as a license in dental assisting. She loves that she can be part of an essential and fulfilling service in her own community.

Sandra has two grown children: her daughter, a licensed CRNA, and the mother of two very special grandchildren; and her son, who owns his own dental practice in Louisville, KY. He and his wife are proud parents of a two-year-old son, and her third grandchild. Sandra is grateful every day for the extraordinary life she has been given!
