Gastroenterologist | Medical Director, Oshi Health | LinkedIn Top Healthcare Management Voice | Forbes Health Contributor

I’m a board-certified gastroenterologist and the Founding Medical Director at Oshi Health, where I’ve had the privilege of helping shape and expand a virtual-first GI care model now serving patients in all 50 states. Working alongside an incredible team, I’ve contributed to building scalable clinical pathways for IBS, IBD, and other gut conditions—anchored in team-based care, empathy, and measurable outcomes.

With 28,000 + followers, I’m among the most followed gastroenterologists on LinkedIn, where I regularly share insights on topics including:

• IBS & the gut-brain connection — emotional triggers, stress, and personalized care
• Digital health innovation — virtual-first models, AI in GI, and wearable integration
• Colorectal cancer screening — rethinking pathways and improving early detection
• Reducing unnecessary testing — CTs, labs, and low-yield procedures in IBS
• Value-based gastroenterology — lower cost, better outcomes, patient experience
• Health plan integration — improving patient access to covered virtual GI care
• Microbiome & nutrition science — evidence-based takes on fiber, probiotics, and gut myths
• Healthcare system reform — tackling disparities, burnout, and reimbursement models
• Behavioral science in GI — the role of habit loops, psychology, and coaching in digestive health
• Virtual care leadership — insights from helping scale a 50-state GI operation

As a LinkedIn Top Voice, I collaborate across digital health, clinical care, and health plans to drive forward-thinking solutions in gastroenterology—without waste, and with humanity.

Let’s connect if you’re working at the intersection of GI, tech-enabled care, or value-based delivery models.
