Dennis S. Riff's Online Review Report Card

I'm writing to relate an extraordinary series of extremely uncomfortable experiences surrounding my colonoscopy, with Doctor Dennis Riff and his practice at Associated Gastroenterology Medical Group (AGMG) in Orange County, CA. I merely wish to draw attention to these mortifying issues and maybe prevent future patients from suffering such experiences.My colonoscopy began with an in-person consultation with Dr. Dennis Riff on October 13th.  He reassured me that he has performed the procedure thousands of times which led me to confidently scheduling the procedure with him for November 3rd at the 1211 La Palma location in Anaheim, CA.On the day of, the office staff and especially Nurse Aislinn were very pleasant, even handing me an extra sheet in the procedure room when asked.  However, upon hearing me ask why the room was so cold, anesthesiologist Doctor Andrew Johnson responded, "We have to keep it cold and it's not like the jungle." As a Vietnamese American woman this comment can only be accepted as racially-motivated.Another unpleasantness immediately followed with the realization that the physician performing my procedure would not be Doctor Dennis Riff as originally expected. As I was processing this series of events, Doctor Johnson injected propofol into my IV line.  He did so in such a heavy rushed burst that it sent extreme pain down to my hand.  I recall involuntarily grabbing my IV arm with my other arm in pain.The procedure started around 11am, I awoke at approximately 11:20am, roughly 20 minutes after. Around 11:30 I was wheeled out to our car by Nurse Aislinn, no physicians checked on me, examined me, or spoke with me regarding the result.After wrestling with my thoughts for two days, I decided to speak to Doctor Dennis Riff to alert him of these shortcomings with his staff.  I was able to reach him over the phone but the conversation only worsened my overall experience.  Doctor Riff immediately brushed off Doctor Johnson's racist comment as simply being "comparing about the climate."  Regarding the lack of post-procedure physician attention, he was likewise dismissive simply saying that they have other patients and things to attend to and didn't want to keep me waiting.  His response about the propofol arm pain would be the most unprofessional thing I have ever heard a medical practitioner utter,  "if you have a complaint about the pain, contact Biden due to the shortage of lidocaine in the country!"It is an understatement to say that the physicians were unprofessional.  More than just breaching the trust that a patient needs from their caretakers, they projected a sense of negligent dismissive hostility. The office and nursing staff treated me with the utmost respect and care.  However, should the physicians' attitudes remain unchanged, I fear many future patients will experience negligence as I did.

Thank Dr Riff and especially THANK YOU to the front office staff.  Lauren has booked all of my son's appointments and has literally bent over backwards to help us. She has been especially kind and helpful. I'm so grateful to everything you and your office have done for my son.  Dr Dennis Riff is absolutely lovely,  kind and patient.

Dr. Riff scheduled me in for a colonoscopy and endoscopy, which he performed. He then ghosted me for 2.5 months, and nobody from his office would call me back for a follow-up. It wasn't until I filed a formal grievance with Blue Shield that his office returned my repeated phone calls. When I went to leave a Yelp review, I saw that Dr. Riff has 4.5 stars. That can't be true, and it isn't. His medical practice, Associated Gastroenterology, has it's own Yelp page, with only 3.5 stars. What a sham, having two Yelp pages!Dr. Riff's behavior is bordering on outright negligence, which is why Blue Shield sided with me on my grievance. I strongly recommend you find another Gastroenterologist.

What an amazing father / son team duo of Doctors Dennis & Brian Riff!!!!!! I have been so impressed with their passion to help me as their patient from day 1. I've only been under their care for 2 weeks and already feel like a VIP.Which doctor's office allows you to come in without an appointment and treat you right away and not wait hours making you suffer for not following their rules???? This one right here!!!!! Seems like this is how you do business. I was seen within minutes between other patients. I was even asked to call Dr Riff on his direct number for bloodwork results next day. Who does that? This doctor gave me his number without hesitation! You gotta love Dr Riff's sense of humor too. He called me a pumpkin thanks to my first time getting jaundice at our very 1st encounter exactly 2 weeks ago. I trust these guys with my life. They know what they're doing even while my liver is not making it easy for them.The front and back office staff is just as amazing. Every interaction has been so pleasant. It's just something you don't see anymore speaking from experience.I highly recommend you see Dr Riff as your gastroenterologist. It's a 2 for 1 special for sure. Thanks guys and have a Happy New Year 2021!!!!! Let's get this year 2020 over with already.

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.

Kind and patient physician: He correctly diagnosed my medical condition and prescribed a drug regimen that cured the problem.

Only had one visit with Dr. Riff for my gallstone issues.  The MD was knowledgeable and personable and scheduled me for several diagnostic tests including an EGD at his clinic office down the hall.  After fasting the entire night, I showed up at 8 am only to be told my insurance wouldn't cover for the procedure.  They offer to do the procedure right now if I were to pay $600 out of pocket.  Hmmm...  I have BlueShield PPO and scheduled the appointment one month in advance so I don't know why it had to come to this.  After more confusion, the office staff learned that they had to submit a prior authorization.  I waited for another month.  Once approved, I called to ask for an estimate of how much I would need to pay.  The office lady said it varies depending on what the doctor finds during the procedure and would not even quote me an estimate.  What?!  Listen, I've been to other medical offices and to see this level of incompetency made me speechless...  I'm sure Dr. Riff has no knowledge of this which is a shame because I really would like to use his service.  I ended up going to another specialist and get my EGD done...no insurance issue and I only had to wait two days to get the procedure done.

Dr Dennis Riff saw my husband Richard Glassman and I can't put into enough words how fantastic he and his great office staff are. Dr Dennis Riff has the great qualities of the type of being a human being when he's talking to you it almost feels like he's your relative with unbelievable knowledge and experience of the best Gastro DR in Southern Ca. He swiftly ordered an endoscopy which my husband Richard had done without a hitch on last Friday and we are waiting for the results but he gave us a preliminary diagnosis before the official lab report. During the endoscopy his nurses and anesthesiology Dr were also fabulous. It was quite a relaxing endoscopy Richard said.

I found this doctor on Yelp and other various health sites. He is smart, patient, nice and professional.

Dr Riff Great doctor he is one of the best doctors I have seen in my 64 years.The office staff is the same 👍👍
