Meet the Doctor

Dr. Faith-Roselle Barreyro — or simply Dr. Faith — was born in San Diego and grew up as part of a proud military family, spending her childhood between Hawaii, Japan, and Southern California.

She earned her Bachelor of Science in Chemistry from the University of California, San Diego, and went on to receive her Doctor of Dental Medicine (DMD) from A.T. Still University’s Arizona School of Dentistry and Oral Health.

Dr. Faith is an active member of the American Dental Association, California Dental Association, San Diego County Dental Society, Academy of General Dentistry, American Academy of Clear Aligners, and the American Academy of Facial Esthetics. She is also a proud graduate of the world-renowned Kois Center, where she advanced her expertise in comprehensive, evidence-based, and aesthetic dentistry.

She is passionate about lifelong learning and continually seeks new ways to enhance her clinical skills — through continuing education courses, podcasts, and dental literature — to ensure her patients receive the highest quality care.

Her philosophy is simple: comfort and trust are the foundation of exceptional dental care. She strives to make every visit a positive and reassuring experience, where patients feel genuinely cared for and confident in their smiles.

Outside the office, Dr. Faith embraces the Southern California lifestyle. She loves going to the beach, staying active through exercise and volleyball, traveling, exploring new food spots, and cheering on her favorite basketball and football teams. Her positivity, warmth, and sincerity shine through in everything she does — and it’s what makes every patient’s visit to Diamond Dental Studio feel personal and welcoming.
