Meet the Team at Oak Tree Dentistry

Welcome to Oak Tree Dentistry!

"Dentistry is my passion and I believe if you do anything with passion, you will enjoy what you do. I enjoy dentistry and I enjoy connecting with my patients. This makes me get up feeling excited to start my day. 

After planning for more than a year, I finally decided to open the practice of my dreams in 2018 where I could practice dentistry the way I want and could make smiles affordable to my patients. Our practice motto is to provide excellent customer service, comfort, and make healthy smiles affordable to all. Due to our commitment to provide quality dentistry and exceptional customer services, we have been voted Best Dental in Elk Grove for year 2019 and 2020. We are also the highest rated office on Google.

We stand by our commitment, 'Your Smile. Our Passion.' I look forward connecting with you."  – Dr. Pritpal Gill
