Mid-Valley Dental

About

For more than a decade, our practice has helped families in Mercedes and the surrounding Mid-Valley communities feel comfortable, informed, and confident about their oral health.

Our Story

Mid-Valley Dental Associates was founded on a simple idea: dental care should feel clear, comfortable, and personal. Over the years, our team has grown—but our commitment to listening, explaining, and treating each patient with respect has stayed the same.

From your first phone call to your follow-up visit, we want you to feel at ease. That means friendly faces at the front desk, a calm and modern office, and a team that takes the time to answer your questions without rushing.

Meet Our Doctors

Our doctors bring years of experience, modern training, and a gentle, patient-centered approach to every visit. From preventive care to restorative and cosmetic treatments, you’ll always be heard, supported, and treated with respect.

Dr. David Lee Treviño

He attended The University of Texas–Pan American, earning his B.S. in Biology, and later began his dental education at Baylor College of Dentistry in 2008. After earning his Doctorate of Dental Surgery, he returned to the Valley, where he has proudly provided patient-centered care ever since.
