Nat S. Bala, MD, FACP, FACG, AGAF Gastroenterologist, Houston, Nassau Bay, Webster, Pasadena, Pearland, TX

“Good health is one of the most prized assets any person can have. And I have found it truly fulfilling to be able to help people make good health a reality and to reduce pain and suffering in their lives. Also, after more than 25 years of experience, I’ve learned that medicine — particularly gastrointestinal medicine — is both art and science. I never forget that each person is unique... including in how their GI problems present and in how they experience those problems. It is therefore vital that I tailor my approach to fit each individual. I expect and demand of myself and all the physicians in my group the very highest standards of excellence, from the quality of care to our efficiency, cost-effectiveness and dedication.”
