This may seem a little informal, but I thought he was a really cool guy! Very nice! Listened to my issues and actually asked some leading questions that got me thinking of other symptoms that I had been ignoring. I feelso much better now about my prognosis and I’m actually looking forward to some answers!

This guy and his staff are so sweet and awesome. And Dr Ast is one of these doctors that knows a ton but doesn’t really let it go to his head. You know you have a doctor like that cause hehas ideas about what is happening based on symptoms and has to pick between a few possibilities. Some doctors jave a pre-conceived idea of what they think you might have based on other factours. Dr Ast is very thorough, easy to understand, and has a wide experience and body of knowledge. It’s hard to find a non-boased doctor who lets the symptoms lead them to the diagnosis. This guy is def on my list of must-have NYC doctors.

Dr. Ast is fantastic. I've seen several primary care doctors since moving to the city, and he is by far the best. Although his practice is busy, I have never felt rushed during an appointment. He always takes the time tothoroughly address my concerns. He's attentive, extremely knowledgeable, professional and compassionate. I can't recommend him highly enough.

My visit and correspondence with Dr. Ast and his office has been awful. I waited over an hour after my scheduled appointment time to see him. The staff was extremely rude and not helpful. My blood results were supposed to comeback within 3 days, I called his office multiple times until he finally returned my call over a week later. Every time I called the people at the office were EXTREMELY rude. He ordered me to get an X-ray and told me he sent the order. I went a few days later only to discover he never sent it. When I called his office the man I spoke with was very and rude and hung up on me. This is by the far the worst doctor's office I have ever been to. I will find a more helpful and professional office.

This is not a review of the doctor but his highly unprofessional office staff. I got a physical from the doctor about a year ago and tried several times to call and get my lab results. 4 calls, 4 times waitingon hold, resulting in 4 times waiting for a call back that never happened. His staff is also extremely rude and treats patients with absolutely no respect to the point of being subhuman. I feel bad since the Doctor Ast is rather good, with a nice bedside manner. It is too bad his staff is ruining everything around it.

The most important aspect about Dr. Ast is that he is compassionate. His staff is also friendly and nice. He is a caring physician that doesn't just rush you out of his office. He is willing to explain to you whatresults mean or could mean and that's crucial if you need further medical treatment or follow up. He makes you feel comfortable and like you're a person not another walking copayment.

Dr. Ast. is great because although he is extremely busy and has a lot of patients, I really do feel like he's giving me his undivided attention for the time I'm with him. I also like that he's a doctor willingto try new things and work WITH you as a partner in the healing process. He doesn't presume to know it all and seems to understand that your opinion and concerns are the most important. A lot of conventional doctors have lost this touch.

Very friendly and professional! As a young person with chronic pain, many other doctors have simply ignored or dismissed my issues. Dr. Ast was much more understanding. I also love that his office has other relevant speicalists like a nervedoctor and physical therpaist. They seem to communicate so that's great!

I would not recommend this doctor for anything. My first appointment took over 1 hour to be seen, the doctor clearly is trying to get you out of his office asap once you do have the chance to meet with him.Post my appointment I needed some follow-ups ordered...the doctor's staff was so incompetent that it took over 3 separate calls from me to remind them that this needed to be ordered. And it still never got done.
