About Maria Isabel Esparza, MD

Who I Am

I am a board-certified physician and endocrinology, diabetes, obesity and thyroid specialist who provides high-quality, personalized care to patients throughout the state of Texas through my telehealth clinic.

I believe in treating the whole person, not just the symptoms. Each individual is unique, and that’s why I take the time to understand your medical history, circumstances, and aspirations.

Education and Experience

I completed medical school in my native country of Mexico at the Autonomous University of Aguascalientes, where I graduated cum laude.

I went on to do my residency in Internal Medicine at the University of Texas Health Science Center in San Antonio followed by a fellowship in Endocrinology and Metabolism at the University of Texas Southwestern Medical Center, in Dallas. 

I also worked for 5 years at the Weight Wellness Clinic at UTSW, focusing on the treatment of obesity and associated comorbidities. I was honored to be an  Assistant Professor of the Endocrinology and Metabolism Department at UT Southwestern Medical Center.


My ability to communicate fluently in both English and Spanish is something I hold dear to my heart. It enables me to connect with a broader range of patients, especially in Texas’ diverse communities. I understand that language barriers can be a significant obstacle to quality healthcare, so I strive to create a welcoming and inclusive environment for all patients. Speaking your preferred language ensures that you fully understand your condition, treatment options, and the steps we’ll take to improve your health.


I enjoy actively engaging with the medical community and I take pride in being involved in organizations that foster diversity, inclusion, and wellness. I was a member of the UTSW Internal Medicine Racial Equality, Diversity, and Inclusion Committee for 3 years, as well as a member of  the UTSW Internal Medicine Wellness Committee.

“I help patients develop a joyful and empowered approach to well-being, a healthy relationship with food, and trust in their bodies.”
