Leticia Johnson

Registered Dental Assistant

I've always loved working with kids because I learn so much from them. I try to take a personal interest in each child I see, remember things we talked about and helping them feel special. In my free time I enjoy camping, watching my son play soccer and my daughter playing softball.

Stacy Summers

Registered Dental Assistant

I was born and raised in the east bay. After earning a psychology degree from San Diego State I started my career working with children living in group homes. I later went back to school to become a registered dental assistant and have been in pediatric dentistry for 11 years. My passion is helping kids see that coming to the dentist can be a fun experience. In my free time I enjoy sports with my three beautiful children.
