Anemia | Biliary Disease | Esophageal Diseases | Gastroesophageal Reflux | Inflammatory Bowel Disease | Intestinal Diseases | Liver Disease | Peptic Ulcer Disease | Stomach Diseases/DisordersI treat all aspects of gastrointestinal and liver disease and strive to provide care with empathy and compassion.
I am board certified in gastroenterology and hepatology. I obtained my medical degree from Robert Wood Johnson Medical School in New Brunswick, NJ, pursuing a research fellowship at the National Institutes of Health in the process. I completed both my internal medicine residency and gastroenterology fellowship at the University of Vermont College of Medicine. I subsequently joined the faculty at UVM as an assistant professor in the division of gastroenterology and hepatology where I served as director of the gastrointestinal motility lab. After enduring a dozen Vermont winters, I returned to western NJ/eastern PA where I have been in practice for the past 10 years, and am delighted to be a part of St. Luke’s University Health Network.
In addition to colonoscopy and EGD (upper endoscopy), I am trained in ERCP, biliary LASER lithotripsy, video capsule endoscopy, enteral stenting, esophageal manometry, intraluminal impedance and pH testing, endoscopic mucosal resection, radiofrequency ablation of Barrett’s esophagus, STRETTA and TIF anti-reflux treatments, as well as HET and CRH O’Regan hemorrhoidal therapies.
When not at work, I enjoy hiking, fishing and gardening with my wife and two children, as well as playing with my two rescue dogs and tending to my small flock of Shetland sheep.

“Since Dr. (Name) retired, I chose to see Dr. Willis as my doctor, because I saw him some years ago when he filled in for Dr. (Name) when he was Ill. Dr. Willis Impressed me with his professionalism and kind, thoughtful manner. Now, like then, Dr. Willis listened to what I had to say and asked questions being very thorough. The staff was also kind and helpful.”

“This was my first colonoscopy and I was understandably concerned/worried about it. The doctor and ALL of the nurses/aides and the receptionists were incredibly kind, patient, and knowledgeable/thorough, and my concerns were completely eased by their level of care. I recommended the doctor to my partner, for his colonoscopy.”

“My experience with Dr Willis and his team was excellent. Everyone was extremely supportive. The young nurse who put in my line for anesthesia was exceptional, just a tiny pinch and no redness or bruising. Heather in the endoscopy/colonoscopy room was very sweet and fixed my pillow without me asking. The Doctor of Anesthesiology answered all my questions as did Evan the nurse anesthetist. I was worried the anesthesia would make me sick.”
