I've never heard of a single person claiming that their gastroenterologist was so wonderful. Dr Yallam goes above and beyond. He is courteous, professional, and makes you feel comfortable about the entire process. I had a large hiccup in the beginning and had to delay my appointment three times. I must have drove the staff crazy with that, but after I was finally able to make it, things were smooth sailing. He is even very prompt.

Barbara MacCollum is a great gastrointestinal Dr. She was recommended by one of her patients who happens to be a friend of my husband and I. She made time in her busy schedule to see my husband when one of his tests came back questionable. She was patient, informative and kind, made us feel completely at ease. As a last thought, we are grateful for Dr’s like her who are compassionate and caring. John and Tena Roberge

Dr Yalan was very professional and answered all my questions; this was my first time seeing him, but he had my previous records and had gone over them. Mattie ( Maddie?) in the front office made my day/ very helpful, friendly and funny. On the other hand , the other receptionists need to take a class on making eye contact, being welcoming and not asking personal questions at the front window! ( hippa rules still apply)
