Primary Care

Whether you’re healthy or struggling, an ongoing relationship with a trusted primary care provider is the critical foundation of our model.

Our doctors were drawn to this specialty because of its unique focus on both preventing illness before it starts, and providing the central role in coordination of care for complicated patients. Without primary care, people end up in specialty care that’s not right for them, getting care they often don’t need, becoming more confused because the system is so complicated.

Regardless of your situation, our primary care providers’ main goal is simple, to maximize the quality of life of the patients they serve.

Meet your Doctors


Deborah Melendez

Dr. Melendez discovered her guiding principle in the jungles of Bolivia. While doing field research on tuberculosis patients, she was stunned to discover that patients weren’t completing their treatment, despite it being fully paid for by the government.

Deborah realized that patients need more than the right prescription. They need the right doctor and the right motivation. Simply, a consultation with Deborah is a masterclass in motivation for the body, mind and spirit.


“I see the whole person not just a medical profile. I treat the whole person not just a medical symptom. Let me help you live longer, happier, and healthier.”


Dr. Melendez is a board-certified family medicine physician. She began her medical career attaining honors in Biology at Wellesley College, before earning her medical degree from Baylor College of Medicine in Houston, TX.

She completed her internship at the Conroe Medical Education Foundation program and finished her residency at The Methodist Hospital in Houston in 2007. Over the past 14 years, Dr. Melendez has worked in private group practices, solo practice, and large federally-funded health centers. She is skilled at managing complex patients with acute and chronic problems.


Dr. Sida Yan
