ERICK ALAYO, MD REVIEWS
Dr.Alayo is a sweat heart. He definitely took the time to understand and give me a realistic weight loss plan and made me feel very comfortable in the appointment. Some doctors can be very rude and judge mental about over weight clients but he was very understanding, professional and polite. The staff was also very friendly and upbeat. I had went to another doctor prior to seeing Dr.Alayo and came back feeling defeated. Going to their office was a breath of fresh air from me being assisted by staff to seeing the Doctor. I would definitely recommend seeing him to anyone.
Excellent Nurses and Doctor. I was extremely nervous going in I could barely hear what everyone was asking me. I have a fear of needles and Cristina really helped me calm down and I was able to relax and focus on my breathing while my IV was being prepped. I remember meeting Doctor Alayo and greeting the Anesthesiologist and then the next thing I knew I was waking up at home. Delightful experience. Highly recommend.
Dr. Erick H Alayo, MD and his staff are very professional and most importantly, very caring. I am very impressed with everyone on his staff. My nurse Chris did an excellent job before and after my procedure. He knew I was a little stressed but he did his best to comfort me. I am thankful I went in because the doctor found one polyp. Don't have any worries going to Dr. Alayo, you will be in good hands!

MARK Y. JOHNSON, MD REVIEWS
I just met Dr. Johnson, I have never felt so important in all my life when coming in for an appointment. Instead of being taken back by a medical assistant, Dr. Johnson took me back he covered all of my concerns, he really paid attention to every word I spoke. Super nice Dr.
I never have met a doctor like a doctor Mark. He is a sweet person who cares about his patients and is very kind and very helpful thanks to God he put this doctor on my way.
I love this Dr. He is very knowledgeable and treats his patients with respect and patience.

GREGORY WIENER, MD REVIEWS
Dr. Wiener is an extremely smart and friendly doctor. He actually listened to me when I described my issues, he didn't talk down to me when discussing treatment options, and he behaved and spoke in a way that showed he cared and was trying to make me feel good. Judy, one of his staff members, was equally friendly and caring and it was easy to see that Dr. Wiener surrounds himself with wonderful, like-minded people. I highly recommend his practice for all your gastroenterological needs!
A smart and wonderful doctor! That staff is friendly and very helpful. Would recommend to any family member or friend suffering GI issues, or in need of a screening colonoscopy.
Very good doctor. Talks to you in a way you can understand everything that is going on with your stomach issues.
