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!!

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.

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.

From the very first visit Dr Rivadeneira was very patient and explained everything so any Layman could understand, The procedure went exactly as he explained and was so quick I didn't realize it was done, I waited 6 years to call his office to have this procedure done, and I can't believe how having the Rubber-band treatment for hemorrhoids has improved my life. His staff was also very helpful and patient.

My experience with Doctor Rivadeneira and his medical staff was exceptional I went to him about a blockage in my colon after completing two colonoscopy’s . He spent the time explaining to me my condition. He even provided me with a drawing showing exactly what his proposal was to correct my situation. His ability to explain and lead in layman’s terms was outstanding. He has a great bedside manner. The doctor and his staff supported me throughout my surgeries. Thank you Dr Rivadeneira

I can't say enough about my positive experience with Dr. R, the Northwell Health Network and my surgeries and stay at Huntington Hospital. I mysteriously (I didn't rip during child birth, do not have gastric disease such as Crohn's) developed a rectovaginal fistula at the rarest possible spot at sphincter muscle. Doctor's near me, upstate NY, wouldn't even touch me. Dr. R first inserted seton drain to strengthen tissue and then performed fix months later. I am success story. I got my life back!

I first met Dr. Rivadeneira when I was diagnosed with colorectal cancer. It was a very frightening time for me. But, from our first meeting he calmed my fears with his kind and understanding manner. He listened and answered all my questions. I was not his patient. I was his family. He is a learned doctor/surgeon. His impressive C.V. is an understatement. I believe Dr. Rivadeneira's mission is saving lives. He saved both my life and my quality of life.
