Dr. Andy Tau is a  gastroenterologist at Austin Gastroenterology with a reputation as both a national thought leader and a dedicated local clinician.

After graduating from Harvard University, Dr. Tau trained for 11 years at Baylor College of Medicine in Houston, where he received the Henry D. McIntosh Award as the best graduating resident, voted on by both faculty and peers.

Since joining Austin Gastroenterology, Dr. Tau has combined clinical innovation with leadership. During the COVID-19 pandemic, he served as a full-time GI hospitalist and was recognized as the 2021 Travis County Medical Society Young Physician of the Year.

Dr. Tau is a nationally recognized expert in endoscopic hemostasis and advanced tissue closure. In 2025, he delivered the keynote address at Digestive Disease Week (DDW), and has served as Course Director for the TSGE, the ACG Leadership Programs, and the ACG Practice Management Summit.

Dr Tau. conceived and pioneered a novel device to rapidly clear blood clots in patients with life-threatening GI bleeding and a game-changing modification to a hemostatic powder that markedly improves its efficacy. He pioneered the use of endoscopic vacuum therapy (EVT) in Austin to treat perforations and fistulas that have no other recourse. He continues to publish in leading GI journals and teach at the largest U.S. scientific meetings every year.

A former college football player, he now enjoys the game as a spectator, but his true passion remains collaborating with colleagues worldwide to develop and advance new endoscopic techniques and devices. Outside of medicine, he treasures outdoor time with his wife and two children on the water around Austin. Dr. Tau speaks Spanish and Mandarin (Chinese).
