About Me
As a gastroenterologist and advanced endoscopist, I screen people for cancers arising from the digestive tract and treat them for complex gastrointestinal conditions, such as cancers, precancerous conditions, and difficult-to-find gastrointestinal bleeding.
I have always had an interest in science and wondered how it can improve people’s health. Gastroenterology appealed to me because even though it involves a variety of conditions, we are able to offer an array of medical treatments and endoscopic procedures to help patients feel better.
I perform endoscopic procedures. These include colonoscopy and upper endoscopy and more specialized ones: endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, spiral enteroscopy, single-balloon enteroscopy, and other interventional procedures to treat problems of the digestive tract.
I also perform radiofrequency ablation and other endoscopic procedures to treat Barrett’s esophagus—a precancerous condition in which the lining of the esophagus changes to become more like the lining of the small intestine. It requires immediate medical attention.
I am proud to be recognized as a fellow of the American College of Gastroenterology and the American Society of Gastrointestinal Endoscopy.
I am dedicated to combining my interpersonal, clinical, and endoscopic skills to help heal my patients. When patients come to see me, I take the time to help them better understand their medical condition. Communication is key to educating my patients about their diagnostic and therapeutic options so they can make informed decisions about their care.
