Kathleen Hartford, RDH

Kathleen obtained her dental degree (Registered Dental Hygienist) from Foothill College in 2010. Her love for clean teeth developed early because she grew up around the dental field with her mom managing a dental office. She enjoys cooking, hiking, reading, and spending time with her loved ones, including her husband and pup, Jameson.


Sonia is a fantastic dentist! I’ve been seeing her for years and appreciate her wonderful personality and top-notch skills — I highly recommend her and her practice.
