Dr. Joanna El-Maasri

I grew up here in San Marcos and moved home after finishing my residency. This community has always been a big part of my life; it has given me to the opportunity to become who I am. I want to make sure that all the children and citizens of San Marcos have that same opportunity.

I became a dentist because I wanted to make a difference in people’s lives. Giving someone a healthy mouth and body, and a reason to smile with confidence, is extremely rewarding. As a dentist, I’m able to truly help people. Getting someone out of dental pain, restoring function, and creating an even more beautiful smile, are all part of a day’s work for me.

Our Doctors

Dr. Constantine Reppas

Professionally and personally, I find the greatest satisfaction in helping people change their lives. Being a dentist allows me to support people: by improving the function of their mouth, removing pain, and creating a healthy, beautiful smile, I am making a positive difference for each patient.

I love that my work introduces me to people from all walks of life. Whether I’m caring for a child at their first visit to the dentist, or giving an adult the smile they’ve always longed for, I’m forming a relationship. We have wonderful conversations during visits, and I find I learn a lot from each patient.
