DENNIS RIFF, MD, FACG REVIEWS

First met Dr. Dennis Riff when I was in the hospital for the third time with C Diff. He seemed genuinely interested in my case and helping me. Since that time, this has continued through a number of visits to his office. Dr. Riff is clearly a cut above some physicians I have met who come into the exam room, spend only the minimum amount of time and then are out the door. Contrasting this behavior, Dr. Riff takes his time explaining my condition and treatment as well as responding to my questions. He is a good man as well as a good doctor.

Dr. Riff and his team of healthcare professionals have consistently demonstrated high levels of care and expertise in their space of practice. Each time I come in to see them, I am greeted with compassion and a care for my wellness I have not experienced with any other healthcare professional. Thank you to Dr. Riff and his team for thier empathetic approach to patient care. I appreciate you.

Dr. Riff was amazing! I was pretty nervous after having a bad experience with another specialist recently, but he was SO kind, warm, and inviting. He definitely is experienced, knowledgeable, and incredible at what he does. I will be referring everyone to him now.

KEVIN KUETTEL, MD REVIEWS

Dr. Kevin Kuettel is the best, and so are his staff and colleagues specially Dr. Riff . When you are with them, you know 100% you are in good hands . They Treats patients with professionalism, respect and patience . The staff at the clinic from the front office to the procedure are (A+) in experience , knowledge and attitude. With then you are not just a number, you feel you are a human and they are doing their best to protect your life I wrote this review after been going there for 11 years and after 6 procedures.

My primary doctor was severely overbooked and the office was short handed. Dr. Kuettel stepped up and took other doctor's patients greatly alleviating a lot of patient anxiety. I LOVED Dr. Kuettel and after leaving his care, felt cared about, respected and listened to! I would gladly switch my care to Dr. Kuettel if the opportunity presents itself.

Dr. Kuettel is a excellent Doctor he listened to all my medical concerns and together we discussed the best treatment plan for me. He is a very thorough Doctor goes over everything in detail. I would definitely recommend him to family and friends.

JASON YIP, MD REVIEWS

Dr. Yip is very professional and patient. I recently had both endoscopy and colonoscopy done by Dr. Yip. His office guides you every step meticulously in preparation for the colonoscopy, from a week before the procedure. They text you with a detailed instructions almost on a daily basis up to the date of the colonoscopy. I was impressed how detailed they were with reminders. Dr. Yip removed 4 polyps during the colonoscopy. I am glad I chose Dr. Yip to perform colonoscopy on me. I have confidence in his skills.

Dr. Yip is a gentleman and is quite thorough in his work. While making detailed notes in his investigation, Dr. Yip maintained constant communication regarding his thoughts with me and made sure I was comfortable with his decisions each step of the way. I do not exaggerate when I say that Dr. Yip was an absolute pleasure to meet and one of the best medical professionals I have met with.

Dr.Jason Yip carefully listens to my needs and does everything he can to ensure I got my health under control.
