    Thank you! Dr.Wolff for taking care of me. Dr.Wolff listens…read moreto you, pays attention and makes precise diagnosis. He knew my medical history even the first time I went..... because he cares. I did my colonoscopy and endoscopy with courage, only because I knew that this doctor is very reliable. I highly recommend him to everyone. Expert in his field definitely. His office is very clean, and the people working there only reflect on the doctor. Aline R.

    Dr. Wolff is the best. He listens to you. He's compassionate. He is thorough when discussing your…read moreCare Plan. And if you look at him long enough you might mistake him for Justin Timberlake (He's been told this btw). He is so friendly and he's pretty good at remembering who you are so you don't feel like you're going to become just another patient in the crowd. His office is located a block away from Grand Central Station so it's pretty easy to get to him. The check in process was a bit confusing to me. I entered one office to check in and the was told to go to another office where I was being expected. When I walked into that office, they had no idea who I was and I had to repeat the process of answering check in question all over again. If Dr. Wolff schedules you for a procedure, it will likely be downtown at Liberty Endoscopy. His staff there is very efficient and on the ball with time management. After prep, Dr. Wolff comes in for a short but sincere chat on what will be happening, how you're feeling, and time to give answers to any questions you might have. The next time you see him, it will be in the OR and he explains everything to you again as well as make sure you are okay. I love that he is so genuine putting his patients first. He or his anesthesiologist will guide you into lullaby land as you drift off to oblivion. And then you wake up to find that everything is done. The Doc comes back to discuss his findings with you after you've had time to shake off the sleepiness. My Gastroenterologist is better than yours...lol.

    This is my second time at this office as this is a follow-up. The office itself was set up really…read morenicely and very clean. The building itself is fairly old as you would see once you enter through the front doors and go into the elevator. No one would guess that there's a doctors office inside of it. They have tea bags plus water coming out of a filter for you to have at the lobby. I've only seen one doctor who specializes in GI issues, but it seems like there's a range of other doctors using the same office. He suggested that I get an endoscopy done and did that at another location at Union Square. Both times, I was seen at the appointed time, but nothing was really resolved. I may go get a second opinion.

    Do NOT attend this practice without verifying your insurance yourself. I saw this practice ONE…read moretime. They billed me right after and again over 1.5 years later for the same service they stated was in network. 1.5 years later they say they haven't heard from insurance for further payment on the one time service . I call my insurance , they said this was taken care of last year, no recent activity was even requested by this practice. I call billing office back to tell them this, get a different person, "oh that was wrong you don't owe anything" hmm...... They called asking why I didn't return to make a follow up appt? Really? Maybe figure this out because this sounds like a billing nightmare and people are given wrong info on purpose to get more money. Just be mindful if you keep going here and whether your insurance truly is in network with this place and get documentation of that. You may not see the bills until well after date of service. Not reassuring for a practice. The doctor was lovely- but sorry my trust is lost.
