I just had a follow up colonoscopy (such an enjoyable experience especially the flush, ha ha) this morning and after putting me out (not just sedation like the first time) I was in and out in about 25 minutes. Dr. Snipped out a sShow moremall polyp and it went smoothly. I will see him again for a follow up in a few weeks. Doc is good at what he does and the Surgery Team on 5th Avenue is just fantastic especially all those kind hard working funny nurses. Make sure they put you fully out.

The nurses were kind and professional and explained everything that I would be experiencing during my colonosShow morecopy and endoscopy. They made me feel secure. This surgical center is very well run and I appreciate every member of the team! Thank you!

The office gave me a QR code that makes every part of my colonoscopy easier, with an AI feature that answers my questions along the way. I think this could really help caregivers too.
