Ms. Monica Elias

Office Manager (Diamond Bar)

Monica grew up in Pomona, CA. She graduated from Pomona High in 1992, and during her senior year she attended an ROP course for Dental Assisting at Baldy View. At first, it was merely an extra credit course, but she gained interest in the field, so continued to learn and eventually became a certified Dental Assistant in August 1993. Soon thereafter, she got married and had two children (1994 and 1995) who have grown into wonderful young adults.

Prior to Horizon Family Dental Group, Monica has worked in a few other dental offices. In May of 1995 when the Diamond Bar doors first opened, Monica was our first dental assistant! The office was brand new - from the floors, to the operatories, to the basic office supplies. The doctors were very welcoming, patient and eager to grow their second family dental practice. Being a member of Horizon Family Dental Office for over 20 years and having the pleasure of serving our wonderful patients has allowed Monica to gain many interpersonal relationships that reach beyond our dental office walls. With staff and families coming and going, it has been a pleasure to watch our unique dental family grow! We feel very thankful for being given the opportunity to treat our loyal patients year after year - some for 20 years! Monica has been dedicated to our practice from Day One until the present time and considers the patients, office, Doctors and the City of Diamond Bar to be her second home.
