Since 1977 our dental practice believes in meeting not only the needs or our patients, but also the needs of our community.

We believe in keeping abreast of advances in dental science, technology, and technique to provide our patients with the best that today’s dentistry can provide.

Treating our patients as individuals and optimizing patient comfort is one of our top priorities.

We are good citizens in the Benicia-Vallejo area as our principle Doctors and many of our staff reside in Benicia or Vallejo. We shop, volunteer, and support the local schools and many community organizations in town.
