Overview
I see patients with a variety of gastrointestinal disorders, including acid reflux, difficulty swallowing, constipation, diarrhea, abdominal pain, gastrointestinal bleeding, and abnormal imaging findings. I also perform a wide variety of procedures in my day-to-day practice, including diagnostic upper endoscopy, push enteroscopy and colonoscopy, and numerous therapeutic procedures. I have expertise in removing large pre-cancerous polyps through a technique called endoscopic mucosal resection (EMR), and I have a particular interest in using technology to improve procedural outcomes. My goal is to listen to my patients, help interpret the scientific literature and other sources of information, make diagnoses, and come up with an individualized treatment plan. My hope is that each patient leaves the office with a better understanding of what is going on and what we are doing to address it.
