"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)"

"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"

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!!"
