“The best!”
I was referred to Dr. Rivadeneira from my Gastro. I’ve suffered with Diverticulitis attacks for about 15 years. I met with Dr R to discuss a colon / intestinal resection surgery. Upon meeting Dr R I felt confident I was in excellent hands. His care team pre and post surgery was responsive, kind and answered all my questions. The surgery was a success. Recovery was just as Dr R explained. I’m so happy with the entire process from start to finish (post op 10 weeks). I would highly recommend Dr R.

“Excellent doctor and very professional.”
I have visited Dr. Rivadeneria a few times and he even performed a surgery on me. The surgery was a success and I had a full recovery. Each time I have visited Dr. Rivadeneira, I was greeted with a warm welcome and had any questions answered before examination. He has a calming demeanor and great bedside manner, this put me at ease for having rather embarrassing problems solved. I would highly recommend this Dr.

“10/10 Amazing Surgeon”
I was recommended to see Dr. Rivadeneira for a fistula that was related to my Crohn’s disease. He was so personable, calm, and confident in his skills. He advised me to schedule surgery for a fistulotomy, and at first I was very anxious but eventually I went through with it, and I am so glad that I did. He was extremely reassuring the day of the surgery, and helpful with all of my questions and concerns. His operating team was fantastic. I highly recommend him to anyone!!

“Amazing Surgeon”
During a routine colonoscopy a cancerous tumor was found by my gastro(Dr. Keschner) who immediately called Dr. Rivadeneira. We were given an appointment 10am the following morning and surgery was scheduled for the end of the week. Dr. Rivadeneira took his time with us and explained everything that was going on and what options I had. I am now 6 months post op and I have very little change in my quality of life and I attribute that to Dr. Rivadeneira and his team.

“UNMATCHED BEDSIDE MANNER”
I recently had several visits with Dr. Rivadeneira due to hemorrhoids. Obviously this is an extremely sensitive area and very painful-- however, Dr. Rivadeneira's delicate care made me feel at ease at these appointments. He had to do a treatment called "banding" and as invasive as this is he made it far less painful than it could have been. He is very kind, professional and caring. His staff is top notch as well. I was always greeted with kindness and happy faces. He is truly amazing at what he

“Diverticulitis Surgery”
After 3 months of wearing a drain for an abscess from Diverticulitis, I was recommended to Dr. Rivadeneira from another surgeon, due to the fact I was considered high risk. Met with Dr. Rivadeneira who explained in detail the surgery I need. He also advised me based on the CT scan, I may need a colostomy bag whether it be for 3 month or the rest of my life since the diverticulosis was spread throughout my sigmoid colon. My surgery lasted about 3 hours and Dr, Rivadeneira skills ensured that I di

“Dr Rivadeneira is the BEST!”
Dr Rivadeneira is the best hands down! He performed a flawless colon resection to remove a diseased part of my colon due to Diverticulitis. I have been 100% since April 2022. Highly recommend Dr R. Great bedside manner and follow up care. Honest and transparent.

“Dr Rivadeneira is very caring, professional and kind.”
Dr Rivadeneira was very patient and explained everything when I visited his office the first time. The procedure went exactly as he explained to me. He was kind, caring, professional, and listened to my concerns. The surge process is very quick and smooth and I am very happy now after the surgery. I will recommend him to anyone having the similar health problem.
