The doctor did a great job talking and suggesting the follow-up tests. He did not even physically access me ( came with the pain). After additional tests- there was no follow-up from the doctor. I had to call the office several times – no resolution. I would not be returning to this office again.

Dr. Olstein performed both my colonoscopy and my endoscope. He made sure I was very comfortable during both procedures. Before and after both procedures Dr. Olstein explained everything in detail. He answered all of my questions that I had. After each procedure he explained the results and what if any other treatments would be necessary.

Had colonoscopy and endoscopy earlier this year. Staff was amazing. Test was completely comfortable (not counting prep for colonoscopy), as I "had a little nap" during it. Both were done in Dr. Olstein's office/testing area. Would definitely recommend!

I recently saw Dr. Olstein for stomach pain I had been having on and off. He was extremely sincere and knowledgeable. He got me into the schedule very quickly for a colonoscopy and was able to quickly diagnose me. I highly recommend him if you are looking for a great GI doctor!
