“I had a close family member who suffered from inflammatory bowel disease. That resulted in my interest in the field of gastroenterology. I am fascinated by the advancements in technology that has now progressed to the point where we can directly inspect every previously hidden part of the human digestive system. I enjoy this process of detection utilizing endoscopy. I am also a good listener, open-minded and very flexible in working with patients. I never give up on a patient.”

“Gastroenterology allows me to combine my interests in long-term and short-term patient care relationships, preventive medicine, performing procedures and conducting clinical research. Treating patients with Crohn’s disease and ulcerative colitis are the diseases in this field that I find most compelling. Each patient is unique and a challenge. I try to know my patients as individuals, and this allows me the ability to understand their symptoms more clearly. When patients feel reassured that someone is listening to their complaints and taking them seriously, they feel validated and protected. I most enjoy being able to positively contribute to a patient’s health. I love when they feel better based upon care that I have provided.”

“Practicing gastroenterology can make a tremendous impact in a patient’s life – which is why I love this field. It allows the best of both worlds- a fusion of traditional medicine which includes listening, examining and counseling my patients – together with that of a more technological approach utilizing endoscopy to better diagnose, prevent and treat gastrointestinal disease. This challenging field is growing and we are learning more each day with new tools to help our patients. I believe educating my patients about their health is paramount. I am a careful listener and detail oriented which helps me to arrive at an accurate diagnosis and tailor the treatment to the individual. I strive to provide the best, most compassionate care possible for my patients.”
