They made an uncomfortable procedure (colonoscopy) bearable for my husband. The doctor, nurse, and staff were very professional and made him feel relaxed and calm. He raved about his nurse Cindy, and said was friendly and personable. You can tell she loves her job and patients. read more

Brought a family member here for a procedure and had a great experience overall. Naina at the front desk was so great at communicating every detail we needed to know beforehand. And nurse Diane was so helpful and communicative post procedure as well. My loved one felt in good hands and received great care at this facility. It's an older building but very clean and the staff are efficient. 5/5 for professionalism and bedside manner from all the staff. Thanks! read more

I can't say enough about this place. At 58, this was a first colonoscopy for me. Between my nurse Cindy, the anesthesiologist and Dr Singh, they were able to make me comfortable with what was about to happen. These people are not only pros, they are funny and understand that as their patient you may be a little nervous and do their best to put you at ease. read more

I can't say enough good things about my experience at AGMG Endoscopy Center! The support staff is friendly and efficient. They even filled out my drug and medication form for me when I thought I could get by with just attaching the long list of meds I take. The doctor who performed the procedure was friendly and attentive, explaining every step of what he would be doing for me. The anesthesiologist also explained everything I could expect before, during and after the procedure. The very best part of the process was having Cindy taking care of me for the post procedure follow up. The world needs more people like Cindy!! read more

Awesome experience with my colonoscopy. Highly efficient and friendly. Staff and nurses were amazing.

I was a few years overdue for a colonoscopy and so I was very very nervous about it. But I knew that at my age, it was essential to have this critical medical check done, so I turned to Yelp to find the best reviewed offices and AGMG was certainly among the top rated, and for good reason. Not only is AGMG very close to me, but this office is absolutely top notch in both aiding in preparing for the procedure, making sure patients are well prepared, but overall the quality of care. I was very scared about everything but everyone involved from the front desk to the doctor and nurses and other medical staff were terrific. Very happy and I'm very grateful for everything. Thank you all so much. read more

My dad just finished his endoscopy/colonoscopy. The type of care he received during these procedures is one that is exceptional. I like to thank Dr. Kevin Kuettel and staff for a very accommodating and professional medical service. Cindy, the nurse, and the other staff were very friendly, supportive and exhibited an excellent patient service. Cindy explained the procedures clearly and took care of my dad vey well.. The reception personnel also gave us a warm welcome. I also thank Dr. Kevin Kuettel and Dr Lee for doing the procedures for my dad. I highly recommend this medical office.. read more

I had a colonoscopy done and the whole experience was great. the staff were very friendly and I felt well taken care of. Special thanks to Tammi! read more

The AGMG endoscopy center is in an older building in the same complex as the Anaheim Regional Medical Center on La Palma. While the waiting area in the front of the AGMG office is small by any medical office standards, it was more than adequate because the friendly staff in both the reception and the back areas moved patients through professionally and efficiently. When I was asked to come into the back for my procedure, I was glad to see that the working area of the endoscopy center, including all of the equipment, was spotlessly clean. My care team consisted of Nurse Tammi, Dr Kuettel, and anesthesiologist Dr Lee, plus a very nice gentlemen who started my IV without any issues, all of whom were wonderful. My questions were answered, and I was treated with care. After my procedure, I was sent home with a document package that included a brief review of my results and clear discharge instructions. I can definitely recommend the AGMG endoscopy center. read more

My dad's experience with his colonoscopy went well because of Tammi, she was very friendly and attentive. RN Diane did amazing with my dad's IV. The doctors were great! 10/10. read more

Great experience for my colonoscopy with AGMG! The prep work was easy with instructions from the AGMG team. Tammi was my nurse and she is super! Thanks to the entire team! read more

Great overall experience with the entire staff that attended to my colonoscopy this past Friday, May 3rd. I was immediately comforted by my fabulous RN Cindy who made me feel welcome and relaxed as she prepared me for the procedure and who stayed with me post procedure. Dr Kevin Kuettel was my Gastroenterologist and Dr Lee my Anesthesiologist. They were both exceptional. Would highly recommend this staff and facility. read more

I am happy that I can leave a five star review, although admittedly my first impression was not good. I was referred for a colonoscopy by my PCP and I spoke to the same man five different times over the course of two weeks to try and schedule an appointment. I was told he couldn't access my information and that I needed my medical group to resend it. Once they did, he then told me he couldn't access it and needed my PCP to send it again. On the fifth and final phone call, he transferred me to the person who then easily booked the appointment. Come to find out all the hoops he made me jump through were unnecessary and he should have transferred me the first time I spoke to him. The day before my appointment we get a call from my PCP office that my insurance assigned me a new PCP. What??? I immediately call my insurance, PCP office and medical group and according to all three, the situation was resolved and I was good to go for my colonoscopy the next day. I didn't want to do all the prep just to show up and find out I couldn't have the procedure. I arrived at 915 for my 930 appointment, explained the situation and sure enough, was not good to go. They needed a new authorization. Estefania in the front office immediately contacted my medical group. I listened to her get transferred, placed on hold and hung up on, all the while she is advocating for me. I couldn't believe how hard she worked to ensure I get could my procedure. After she kept getting the runaround, finally around 11 I heard her say " we got it!". Not only was I appreciative for all her efforts but to the staff who still accommodated me and by 11:15 I was called back to get started. The staff was amazing. Nurse Cindy made me feel comfortable and I knew I was in good hands. The doctor and anesthesiologist introduced themselves and answered any questions I had. Before going under, I mentioned how thirsty I was. After the procedure, which went well, I was in the wheel chair ready to head home and the anesthesiologist saw me, remembered I'd said how thirsty I was and brought me water. Thankfully, after the frustrating experience of trying to book the appointment, and all the nonsense with my medical group, I can happily say this place and the staff were wonderful. My husband is due for his colonoscopy and we feel much better knowing it will be here. Thank you to Cindy and Estefania for all you did to give me a good experience! read more

Had my procedures here Dr Riff is the best of the best, wouldn't go anywhere else. Nurses were all nice, polite and welcoming. I was in and out in an hour half. Estephany at the desk was very helpful. Thanks for always taking care of me!! read more

Well shoot, not sure how to write a review after having a colonoscopy, but here goes. This was extremely great care, the nurse was so patient and informative, the anesthesiologist was super nice, and the doctor was on point. Everybody was great from beginning to end. I'm glad I found this place. read more

Impressed! Except for having to wait in the waiting room for an hour after I arrived at the appointment time. The staff was great! I especially salute the nurse Cindy and the anesthesiologist. They were very caring, professional and I knew I was in great hands! I'd definitely this this place is a cut above the rest!!! read more

To say that I was nervous for the endoscopy colonoscopy would be an understatement. Had procedures done today and could not be happier. RN Cindy was fantastic. She kept me calm, explained everything in detail and in general made a scary situation better. From the anesthesiologist ( my new best friend) to Dr. Brian Riff I realized I was in the best possible hands. I would recommend these folks to anyone. I will never go anywhere else again. Thank you all so very much! read more

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!!!!! read more

Agmg Endoscopy Center - Gastroenterologist Near Me - Anaheim, California

My colonoscpy went well and was quick and painless even though my health insurance denied the anesthesia where you sleep though the procedure. Cyndi was a great nurse, very caring, supportive and loving. She deserves a big raise. The front office staff was efficient and the entire process ran very smoothly. Thanks AGMG Endoscopy team John "Scott" Lewis read more

They were all accommodating AGMG staff is the best!!! AC Castillo read more

I was very nervous about going in for my "double" but the staff is so caring. Both Dr.Riffs are great drs. The anesthesiologist was very comforting. The nurses were great but Tami, there aren't enough words to describe how wonderful she was, if it wasn't for her I might've tried to sneak out. She was the best read more

Thank you for taking care of me with kindness today. Georgia read more

This was such a pleasure experience. I came with nervous, but when I saw Cindy my half nervous was gone. She is so kind and warm, she prepared everything before the procedure. After I was in the room, second later I was feeing nothing . And half hour later it was done without any feeling! That's incredible. After the endoscopy, you can drink water and eat right away, isn't that easy? read more

I had a colonosopy and and endoscopy at the same time. I was told that they call that a "double header." Dr. Brian Riff did the procedure and he was fantastic. He had great bedside manner.

Went in for a colonoscopy this morning. Staff was so friendly and professional. Would highly recommend this facility. Everything went smoothly, from contacting me before my appointment to confirm my understanding of the prep process, to answering all my questions, to checking me in and pre-procedure prep, to post-procedure care, everyone and everything was done so thoroughly and with such kindness and courtesy. Colonoscopies are never fun, but the staff here made it the best experience I have ever had. Thank you so much! Special thanks to Nurse Cindy D. and Dr. Dennis Riff. read more

Dr Dennis Riff and his entire staff were thorough and professional through the whole process, from initial consultation until procedure was completed. Very organized, out the car and back into the car in 2.5 hours. They provided a nice binder review and summary of the process with some great colorful action photos as well! returning in 5 years for sure. Thank you Team AGMG read more

Commendations to the staff at AGMG for a comfortable endoscopic examination. Once admitted to the procedure area, I was treated royally, especially by my dedicated nurse (Huyen) who attended to my every need, including conversations to fill the short waiting periods between prep and the actual procedure. I was told the procedure was low risk and simple, but it is unnerving going under full anesthesia , even for a short time. For me, it was a little challenging to get my first appointment, and I did have to follow some strict guidelines starting 7 days before your procedure, but once I met those guidelines are, the process was quick and painless. I recommend AGMG. read more

Went in for a Colonoscopy. Was taken great care by all the staff. Tammi and Daisy took great care of me before & after procedure. Anesthesiologist explained everything and put me at ease. Dr. Brian Riff spoke to me before and after procedure. Would highly recommend the Anaheim office. Thank you to all of you! read more

If all my medical procedures were this seamless, I would never worry. After numerous years of only taking the Fecal Globin test, this was my first colonoscopy. The prep instructions provided by AGMG were very clear and easy to understand. The procedure itself was quick, easy, and painless. The AGMG staff are GREAT, pleasant, and very professional (treat you with dignity). Dr Dennis Riff is very kind, professional, and friendly. I highly recommend AGMG for this procedure and believe the quality of service will still be high for my next colonoscopy in 10 years. Great job AGMG and keep up the good work. read more

Good overall experience. Everyone throughout the process was knowledgeable, friendly, and professional.

Annual visit for colonoscopy. The staff are so kind and attentive. They make this unpleasant experience surprisingly comfortable. If you need this procedure done, Dr. Wheeler was fantastic. read more
