"THE SNOOPY DENTISTPediatric Dentist Walnut Creek, CA - Dr. Duane Spencer"

Why Snoopy and Pediatric Dentistry?

In 1967, while serving with the Navy in Japan, Dr. Spencer treated the dependent children of Navy families stationed overseas. He hung a smiling Snoopy greeting card from his dental light & found it worked wonders with the young patients. Snoopy has been Dr. Spencer's dental "mascot" ever since. This office contains hundreds of Snoopys and Woodstocks which both patients and parents enjoy and for this reason is often referred to as the "Snoopy Office" or "The Snoopy Dentist". Patients wearing Snoopy shirts, etc., or bringing their favorite Snoopy toy with them to the office can expect to have their picture taken for the wall. In 1983 Dr. Spencer drew the "dog house-dog bowl with toothbrush" logo that this office continues to use. He opened this Walnut Creek pediatric dental practice in 1973. Dr. Spencer named his practice Walnut Creek Pediatric Dentistry in 1995. In 1990 Dr. Spencer received a personalized and autographed poster of Snoopy with braces from Snoopy's creator, the late Charles Schulz.
