Dr. Ezra H. Kantor
OUR LEGACY & RETIRED PROSTHODONTIST
Dr. Ezra H. Kantor graduated from the New York University College of Dentistry in 1972, achieving membership in Omicron Kappa Upsilon, the national honor society for dentistry.
He restored implants for more than 25 years of the 42 he practiced, placed his own for more than 20 years, and is a Fellow of the International Congress of Oral Implantology.
He became a dentist because he enjoyed working with his hands. He paints, draws, sculpts, and makes models. Ship models have recently been of particular interest. He also likes to read history. He is especially interested in the American Civil War period.
He and his wife, Jill live in Petaluma, California where they play Bridge and dance West Coast Swing. He and Jill have three grown children. His son Dr. Grey, a Fellow of the International Congress of Oral Implantology and a member of the dental honor society Omicron Kappa Upsilon, took over the practice following his retirement.

Sam Fullerton 
REGISTERED DENTAL HYGIENIST
She always loved the dentist as a kid and knew she wanted to work in Dentistry from a young age. When she found out some people don’t love the dentist or have fears, she wanted to ensure people feel comfortable, safe, at ease and maybe even have a little fun when they come in for their cleanings! She is a third-generation Bay Area native and lives in Terra Linda. She has a daughter Presley at Vallecito School. They have fun volunteering with their girl scouts troop, hiking with their Labradoodle Dolly, camping, traveling, swimming and dancing to live music. Sam is originally an A’s fan, growing up in the East Bay but also has lots of love for the Giants.
Dianna Castaneda
REGISTERED DENTAL HYGIENIST
One of my favorite things about being a dental hygienist is teaching my patients that oral health is whole health. A healthy mouth is the foundation for a healthy body and a confident life. I love helping them understand that connection and empowering them to take charge of their well-being. At home, I cherish time with my family, and nothing resets me like a weekend camping trip at Feather River, floating on the lake with my headphones and some good music!
