Meet the doctor

Dr. Sierra was born in San Francisco, raised in Los Angeles, and found his way to the Central Coast after meeting his wife — a Central Coast native — as an undergraduate at UC Santa Barbara. The Central Coast has been home ever since.

Dr. Sierra received his dental training at Western University of Health Sciences' College of Dental Medicine, followed by a General Practice Residency at the Veterans Administration in Memphis, TN — where he was actively involved in hospital dental care for adult and geriatric patients. He entered private practice in 2015.

What draws Dr. Sierra to dentistry is the intersection of form and function — care that looks right, feels right, and holds up over time. He approaches each patient with a thorough evaluation of tooth condition, bite, function, gums, and appearance, then works collaboratively to develop a plan that fits each person's goals.

Dr. Sierra meets regularly with other general dentists and specialists to stay current with evolving standards and techniques in dental medicine — because the best outcomes come from ongoing learning, not just what was true at graduation.

Our philosophy

How we think about your care

01
Evaluate thoroughly
Every plan starts with a complete picture — teeth, bite, function, gums, and aesthetics — so nothing is missed and nothing is rushed.
02
Plan collaboratively
We work with you, not at you. Your goals, timeline, and comfort shape the treatment plan as much as the clinical findings do.
03
Think long-term
The best dental care is care that lasts. We weigh durability, aesthetics, and function together — not as trade-offs, but as a unified goal.
