"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)"

"Dr. Yalam is one of the nicest doctors that I have ever met and I'm glad that he's the one I had my first (and only) colonoscopy with, as I was very nervous about the procedure. Dr. Yalam correctly and immediately diagnosed my GI issues as being caused by excessive bile, prescribed an appropriate medication, and I now have a new lease on life; it changed everything."

"There was no waiting for the doctor in the office. Dr Yalam came into the appointment reviewed my chart with questions and went over all the details of my visit. This is my second visit over the years. Dr. Yalam has a great bedside manor which tells me he is confident and happy at his job! Which I’m not sure a lot of our health professionals can say today."

"I’ve been a patient of Dr John Wells over thirty years now and would recommend him highly. He diagnosed my Ulcerative Colitis in 1990 and has cared for me through every flare up, hospital stay, colonoscopy and medication change with kindness, consideration and successful remission. He and his staff are top notch in my book. John Scott Fitzgerald"

"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"

"I have been a patient of Dr. YALAMS for a least 20 years. Probably longer. Excellent physician! He takes the time to sit down and explain everything! When I have had procedures scheduled, I am so comfortable in his care. Dr. Yalam has a wonderful person who you may see after the appt with him. Her name is Mattie. She schedules procedures and any other things for him.. She has been with him for as long as I can rrmember. She also is amazing!!"

"Dr Yalam immediately knew that my problems was a bacteria in my stomach and instead of guessing how to kill it, he took a sample and sent it to a lab to determine what antibiotics were needed to kill it. My previous doctor had been working on this problem for over a year."

"I have had ear issues for over 40 years now. I always get anxiety issues when I have to go in for these check ups and any procedures. Dr. Yalam has some of the best bedside manner’s that I’ve ever had the pleasure of receiving from a doctor. He explained, step-by-step, the procedure that we were going to move forward with. Then he also offered a Plan B and plan C if my nervousness would not allow me to complete the first recommended plan. The procedure went much better than I had anticipated and actually didn’t take near the time that I thought it would. I would highly recommend Dr. Yalam and will no longer go into an ear exam or appointment, with the nervousness that I have had for many years in the past. I can’t thank you enough, Dr. Yalam, for the care you provided. All the best to you and your staff"

"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."

"Dr Michael Foley is one of the most knowledgeable and caring doctors we have known. He is so kind, gentle and took the time to listen answer all questions we had completely. He treated my mom while she was in the hospital at Honor Health -John C Lincoln North Mountain. She was very sick and he made the best of a very difficult situation. I would recommend this doctor to anyone. If I ever need a GI doctor... he will be my first choice. Thank you for being such a great doctor and caring person!!"
