Dr. Ralph Reyes

Dr. Reyes & Dentistry are a perfect match! From the beginning of his college days he was destined to become a dentist.  Initially, a pre-med student interning at the San Diego County Hospital,  Dr. Reyes entered into the Dental Department out of curiousity.  From that day forward he has committed himself to Dentistry and his passion for the Arts and Sciences has never faded.  After graduating from UC San Diego with a degree in Microbiology he attended UC Los Angeles to complete his Doctorate education in Dental Surgery.

Dr. Reyes has always practiced in Azusa and recently celebrated his 25th year in practice and is now in a new facility in Downtown Azusa.  “It was always my intention to practice in San Diego because I fell in love with it while fulfilling my undergraduate education, however, fate had a different plan for me”.

In 1986 Dr. Reyes acquired a 30 year old practice from one of Azusas premier dentists, Dr. John V. Moller and over the next three years Dr. Reyes also acquired adjacent practices from longtime dentists Drs. McChesney and Antle.  As his practice grew Dr. Reyes focused on restorative and implant dentistry and also affiliated himself with Specialists providing Endodontic, Periodontic, Orthodontic and Implantology care.

For almost as long as Dr. Reyes has been practicing dentistry he has been married to Jeannine, his lovely wife of 23 years.  Their son Angelo, is completing his second year of college in San Diego but has no intention of becoming a dentist and is considering lawschool.  The Reyes family make there home locally where Dr. Reyes enjoys everything and anything outdoors but finds most of his time is committed to his yard.
