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, 2020 and 2021. We are also the highest rated office on Google in elk Grove.
After 4 years of serving Elk Grove community, we decided to expand and open our 2nd location in Lodi. We have many patients, including our valued senior citizens, who commute from Stockton, Lodi and Galt. We wanted to be more easily accessible to all our patients and provide same quality dentistry in Lodi.

I love to find ways to help people smile and that includes building confidence to share their smile! I am happy to answer your questions, plan for appointments, help resolve concerns and make your visits positive. It is important to me that each of you enjoy a feeling of ease and confidence in our office. Outside of the office I am a busy sports mom always rushing to practices, and coaching my daughters team. In between sports and work I love spending time with my husband and our daughters doing movie nights, camping trips or traveling.
