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.

I had a colonoscopy 5 years ago and I felt so violated. So this year I was so lucky to get Dr. Sunny Lo to do my colonoscopy and endoscopy the same day, I was kept very comfortable and the Dr explained everything to me. I got my rShow moreesults and I am very healthy, will go back to Dr Sunny Lo any day. His staff is also super awesome.. I highly recommend Dr Sunny Lo to everyone, he is so awesome and very handsome. Thank you

Very good experience and an excellent staff working with him. Highly recommended. This comes from one Doctor to another.

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.

The waiting is a little long but the overall review of the operation is very good, went thru what have been done and the results of the findings is negative ( no sign of any cancerous symptoms in those polyps).
