Dr. Richard Trevisin was born and raised on Long Island, New York. After graduating high school he moved to southern California where he completed his Bachelor of Science degree in biologic sciences. He attended Los Angeles College of Chiropractic and graduated magna cum laude with his Doctor of Chiropractic degree.

In 1979, Dr. Trevisin opened Rancho Bernardo Chiropractic & Wellness Center, and was the first chiropractic office to permanently establish itself in the community. He has continued to practice here for 30 years.

He is an active member of the Rancho Bernardo Business Association.

It is our goal at Rancho Bernardo Chiropractic & Wellness to help as many people as possible, young and old alike, to reach their full potential through quality, affordable chiropractic care.

Dr. Mamerto A. Estepa Jr. brings a joy and passion about living that infects anyone he meets. He grew up in Oxnard, California and attended UC Berkeley, where he earned a Bachelor of Science degree in civil engineering. He then managed municipal construction projects for 8 years. 

During that time, he became a chiropractic patient. Unusual back pain after training Brazilian jiu-jitsu prompted him to initially seek mainstream medical care. Painkilling shots were recommended for treatment. Knowing that shots would only mask the pain, not correct its cause, he decided to try chiropractic .

Chiropractic succeeded in relieving the back pain. As he continued receiving chiropractic adjustments, he noticed improvements in his physical training and overall health. He realized that chiropractic helps people get better and keeps them at their best. Inspired to share chiropractic with others and to serve his community differently, he decided to become a chiropractor.

He attended Cleveland Chiropractic College Los Angeles, where he was named Senior Intern at the Venice Family Clinic (the busiest free clinic in the US), and graduated as a Doctor of Chiropractic.

Dr. Estepa is committed to expanding his clinical skill. He is currently completing a postgraduate certification program in providing chiropractic care during pregnancy and throughout childhood, through the International Chiropractic Pediatric Association.

Dr. Estepa lives in North County with his wife Karen. He enjoys being active, exercising at the gym, riding horses, practicing martial arts, and playing with his nieces and nephew. He loves shopping for fresh, organic produce and creating delicious, yet healthy meals for his wife.

Dr. Estepa is excited to join Rancho Bernardo Chiropractic & Wellness and looks forward to helping others achieve their health goals, become healthy, and live well through chiropractic.
