Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

My sister was a patient of Dr. Riff's. I say WAS as she had a massive stroke on March 18, two days after she had an MRI for her MS which was primarily located in her neck, and I guess no one could get around to reading it before the stroke hit. I am sure the signs were there as she complained of terrible headaches. But I digress. Dr. Riff did NOT care for my sister, and labeled her an addict and for that she received inadequate care. Dr. Riff discriminated against my sister for her addiction issues, and even after her MS diagnosis he managed her pain medication (not her pain) in protection of himself, not her. This man failed my sister in her need of medical care and instead labeled her an addict and marginalized her as not being worthy. You should only go to this man if you are healthy. He's not good with sick people.

Dr. Riff is kind and attentive to what is going on in your life that may be affecting your disease process. He is always happy to see you and is very friendly. I feel so fortunate that He is the Dr. that I was assigned to, would not want any one else!

Dr. Riff...My colonoscopy on the 1st was completely uneventful with good results. You should know, aside from your expertise and wonderful presence, your Nurse Aislinn (Ace) Sidling was just wonderful in the follow-up. She cared, she was warm, and she called just as she promised. You have an all star team in Cindy and Tammy and their staff. Thank you for excellent care and the warmth and caring of your staff. Bravo! Gail

Dr. Riff has been my PCP for about 10 years. I always feel like he listens to what I am saying and takes as much time as needed for a proper diagnosis and explanation. They truly don't get any better than this guy. Even his staff is wonderful.

Fair rating is a gift for this Dr. ON THE DAY OF THE PROCEDURE we expect to see Dr Riff. He has the gall to send another MD in his place! He NEVER checked with the patient 1ST! After the procedure HE NEVER CHECKED ON the progress or even made a common courteous phone call ON HIS OWN PATIENT! If he works for you so be it. I would NEVER recommend any Dr that has this kind of attitude toward his patients!

Dr. Riff was amazing! He listened and he made my priority a priority during the initial consult. He knew I had an ulcer right away, but still recommended I had an endoscopy STAT to rule out anything else. Dr. Riff is an awesome doctor and feel blessed to find him!
