Dr. Kevin Cabugao

General Dentist at Napa and American Canyon/Director of Hospitality

"Because of my commitment to excellence some have labeled me as somewhat of a perfectionist... Although true to a certain extent, I disagree. Without the fear of being wrong, I sincerely care about everything I do and try my best to do it well.”

Born in Hawaii and raised in Vallejo, Kevin Cabugao received his BS in Genetics at the University of California at Davis and worked in biotechnology before refocusing his energies towards graduate school. While Kevin found his work in the pharmaceutical industry rewarding, he felt unsatisfied with his career and sought an education that would best complement his enthusiasm for helping others with his understanding of the sciences. With this intention, he received his MBA from California State University East Bay and DDS from the University of the Pacific School of Dentistry. Currently, he is an active member of the American Dental Association, California Dental Association, Fortune 50 and serves as the President of the Napa/Solano Dental Society.

When away from the office, Kevin enjoys listening to music, snowboarding and honing his mixed martial art as a 4th degree Kajukenbo black belt with over 30 years of experience! Dedicated to treating you and your loved ones like family as the Director of Hospitality, he can be quickly reached through our Marina Encore Dental phone app by clicking on this link!

Dr. David White

General Dentist at American Canyon

Dr. White, a native Californian, grew up in Marin county from age 10. As a boy scout, he learned about the outdoors and hiking and camping. At around age 14, he decided that a helping profession was where he was called and has never wavered from his choice.

After attending college in Colorado (reflective of his love for the outdoors), he returned to California and graduated from University of the Pacific in Stockton. In 1978, he began his training at University of the Pacific School of Dentistry and obtained his DDS degree in 1981. He began teaching at his dental school, UOP, right after graduation and taught one day a week for 24 years.

In 1982, he started as an associate dentist at Marina Vista Dental and in 1987 became an owner in the group practice. Through several transitions while eventually making partnership, he soon became the sole owner of Marina Vista Dental.

A new partnership was formed with Dr. Kevin Duquette in 2006 and has continued to this day. In 2019, Marina Vista Dental then relocated to American Canyon at Encore Dental.

Dr. White is proud to be married to his wife Judy for 45 years, he has two grown children a Veterinarian daughter, and a son, a distributorship manager for Boars Head in Oregon. He remains active with bicycling, hiking and camping (with the comforts of a motor home however).
