Dr. Vivian Asamoah - certified gastroenterologist

I believe that the journey to long-lasting, optimal health begins with nurturing the mind, body, and soul. A harmonious blend of science, lifestyle, nutrition, spirituality, and community support helps achieve this goal.

My mission is to provide comprehensive gastroenterology and hepatology care with a focus on the whole person, connecting the whole system by educating, preventing disease, and empowering each patient to live their best possible lives.

Early on in my medical career, I was fortunate to learn the art from diverse viewpoints and approaches in some of the most reputable medical institutions around the globe. I completed my medical school training at the University of Geneva, an innovative healthcare system with a strong focus on homeopathic, osteopathic, and nutrition in the delivery of care to our patients.

My time in fellowship in Gastroenterology, Hepatology, and Nutrition at the world-renowned Johns Hopkins Hospital is where I became skillful in cutting-edge, state-of-the-art diagnostic and therapeutic interventions that underlie the specialty. It is also at Johns Hopkins that I met lifelong mentors like Dr. Gerry Mullin, Dr. Robynne Chutkan, and Dr. Linda Lee who have played pivotal roles in shaping my knowledge and passion in Integrative and Functional Medicine.

The practice of gastroenterology provides preventative, diagnostic, and therapeutic solutions to many illnesses, however, in the past 15 years, I have also come to know some of its limitations. Performing diagnostics and prescribing medications alone pales to spending quality time with a patient to help identify and understand the root cause of their ailment. Functional Medicine training from the Institute of Functional Medicine has broadened my perspective as a physician. It has helped me connect the dots between the field of gastroenterology and other systems such as the microbiome, endocrine, immune, neurological system, and so much more.

It is an exciting time to be in medicine today where we are developing tools to help understand the whole patient and the multi-system interconnections to better prevent, treat, and reverse chronic disease.

My hope is to meet every patient’s needs by bringing a different kind of gastroenterology care to our Katy community and Houston as a whole. I am grateful and honored to serve you, my patients, as a practitioner, educator, and also importantly, your advocate.

“I looked around a long time for a doctor that I was comfortable with, and Dr. Asamoah was worth the wait. I appreciated how precise her questions were — not general “how are you feeling” types of questions. I also like how she’s not quick to prescribe (which may cover up an issue) vs. figuring out how to reverse an issue.  Very kind, patient, and thorough — what I want in a doctor.”
