I had a colonoscopy done there two days ago, and the staff was just remarkable. Everyone was very kind and helpful Dr. Sie was very kind answering any questions I might have. I felt very comfortable with him. He’s a great doctor. I would recommend Florham Park Endoscopy Ctr. to anyone and everyone I know.

There are not enough positive adjectives to describe my experience or the staff at Florham Park Endoscopy Center. My experience could not have been better. Having the right doctor and staff means the difference between having a so so experience and having a great experience. I had a great experience there. I would highly recommend anyone on the fence about waiting, don’t put it off. This team makes all the difference. They are professional, warm, caring and know what they are doing. I’ve had reflux for thirteenth years and it was confirmed in a 30 minute procedure and with one pill every day it’s gone. Thank you everyone associated with my care. You’re all awesome professionals and tops in my book.
