About
Michael Bass, MD is Viome's Chief Medical Officer and a board-certified gastroenterologist/hepatologist. He trained at St. George's University, completed internal medicine residency at Georgetown University, and finished gastroenterology fellowship at SUNY Downstate. His background includes clinical practice at US Digestive Health, early capsule-endoscopy work, and Founding Medical Director experience at Oshi Health, where he helped scale virtual GI care. At Viome, that GI background supports the clinical posture around microbiome testing and precision nutrition.
What to Know
Signature approach
Bass's Viome role is clinical translation: connecting RNA-metatranscriptomic microbiome testing to the way GI clinicians think about digestion, inflammation, nutrition, and follow-up. His prior virtual-care work at Oshi Health gives him a practical lens on how test results become usable outside a traditional clinic visit.
What sets them apart

- Virtual-care builder. At Oshi Health, he helped scale a GI platform across all 50 states.
