Tomoko Gerbino – Registered Dental Hygienist


As one of our Registered Dental Hygienists, Tomoko has 10 years of combined experience in administrative roles, dental assisting, and in dental hygiene.  She developed an early passion for the dental field when she served as a volunteer for a U.S military dental clinic in Okinawa, Japan. She has always been interested in understanding the world beyond our individual experiences which led her to graduate with a B.A at San Diego State University, where she focused her studies on human behavior, specifically how people interact and behave with each other.  This all led to Dental Hygiene School in California at Concorde College and receiving her dental hygiene degree in 2018.
Tomoko believes that oral health plays a fundamental role in a person’s overall health and quality of life. One of the most rewarding aspects of her work is the opportunity to develop strong relationships with our patients. She understands that many individuals may experience anxiety or fear when visiting the dentist and she strives to create a warm and welcoming environment that eases their concerns. 

“I love how the Sweet Spot Dental team operates with empathy and compassion while providing exceptional dental care. The genuine care and concern for our patients’ well-being is evident in everything we do. I’m proud to be a part of a team where I can continuously learn and grow while making a meaningful impact on our patient’s oral health.”

Tomoko is a fellow foodie and an oat-milk latte and dirty chai addict. She enjoys traveling to learn about and experience new cultures. During her downtime, she enjoys taking her film camera and exploring while photographing new places with her husband, Jacob, and their Goldendoodle, Mochi.
