Professional Background

Dr. Merlyn Thomas earned her Bachelor of Science in biomedical sciences at Texas A&M University in College Station in 2012. She earned her Doctor of Medicine in 2016 at Paul L. Foster School of Medicine, Texas Tech University Health Sciences Center in El Paso. She completed her Obstetrics and Gynecology residency at The University of Texas Health Science Center at Houston in 2020, where she served as administrative chief resident in her final year.

Professional Associations

Dr. Thomas is a member of the American Congress of Obstetricians and Gynecologists, the American Medical Association, and the Harris County Medical Society.

Hobbies and Interests

Dr. Thomas enjoys reading science fiction novels, spending time with family and friends, watching documentaries, and trying new restaurants and new foods.

Fun Facts

The best advice Dr. Thomas has ever received is: “Be kind to people because you don’t know what battles they may be fighting in private.”

Her guilty pleasure is watching reality television, such as the “Great British Baking Show.”

As a child, she wanted to be a U.S. senator when she grew up. She loved the idea of working with people to create policy that would improve the lives of people in her community. She realized she prefers the sciences and is now helping her community in a different way than she planned!

​My philosophy of care is to treat each patient as if she were my mother, sister, or daughter and to give her the attention and expertise that I would wish for them to receive. I want to provide the best care to women through all phases of their life from pregnancy to providing excellent gynecologic care. I feel it’s a privilege to focus my whole career on providing the best care to women of all ages.
