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.

Ms. Carol Medina

Office Manager (Panorama City)

Ms. Carol Medina has been a current Panorama City resident for over 24 years and considers the city as her new home from the Philippines. In her native home of the Philippines, she served as a Registered Midwife. When she immigrated to the US, she took up a new career in dentistry beginning with a radiology license. She applied for a position at Dr. Yolly's brand new dental office in January 2000 and the rest is history. Carol has been an active member of Markgondon Cavite Association of Southern California for many years where she can reconnect with old friends as well as create new friendships. 

Ms. Elizabeth Montes

Dental Assistant

Liz was born in Glendale CA, graduated from Nogales High School and went to the American Academy of Dramatic Arts. She grew up in West Covina for 30 years and is the youngest of four. She picked up a career in Dental Assisting at Hacienda-La Puente Adult Education School through their dental program with one of the greatest instructors she has had - Ms. Gretchen Richardson.

Horizon Family Dental Group has had the pleasure of having Liz as a faithful and dedicated member of our dental family for 19 years! She has had the pleasure of watching our patients and dental practice grow throughout the years, and is grateful for all our patients who continue to come here along with their growing families. Liz is especially grateful to patients who recommend their family, friends and co-workers to share a comforting dental experience with us after having been traumatized somewhere else in the past. It is very rewarding to know that our patients can confidently refer their loved one to us, knowing they will be in good and caring hands with our dental team.
