JOHN J ACKERT, MD

Google review (Pcf Nyc): I want to express my gratitude to Dr Ackert for seeing me through a difficult time that ultimately required surgery. Dr Ackert was instrumental in diagnosing my condition, choosing a top surgeon and putting me on a sustainable path to a full recovery. He helped change my life for the better. I’m beyond thankful to Dr Ackert and his assistant, Yanique for everything!!

Google review (Michelle Leibowitz): Dr. Ackert is one of the kindest, most caring doctors I've ever had! Aside from making me feel very comfortable, he was extremely accommodating and competent-- he squeezed me in and performed a last-minute endoscopy on me that same day. Very grateful and would highly recommend!

Google review (Alcarinque R.): Dr. Ackert himself seems lovely, the one time I managed to meet him in person for an endoscopy. The problem is that his office is the most infuriating one I've had to deal with. I'm not a problem patient calling nonstop or requiring high-maintenance service, either. Over the past 3 weeks, I was given the wrong procedure prep and had to figure that out on my own (and didn't get a call back until I emailed them), I had a pharmacy call me and tell me I had a prescription but the doc's office never told me what it was for and why (and I'm still trying to find out, but again, the office responds to no emails OR calls), and the only reason the endoscopy got scheduled to begin with is that my primary care physician works in a related practice and submitted the referral directly - I couldn't get an appointment by calling on my own because no one replied for days. I've never had a call *not* go to voicemail (and I've never gotten a call back after leaving a message). I'm fed up, still in pain, and exhausted.

Google review (Gail Katz): Excellent nurses, doctor, facility. Ive had Dr. Ackert for my colonoscopies for 20 years. On 2 occasions, I needed care before I could have the procedure. I was brought to a bed, guven heated blankets, monitored, given a drip. The procedure wasn't started until they were sure that my vitals were perfect. I highly recommend this doctor and facility.
