They were very busy when I came in to the office but they worked very hard to get everyone seen. Dr. Ast was wonderful as well as the nurse!. The only thing I didn't like was he asked me to send my medical records, normally the doctor obtains those from the hospital! Otherwise I will keep him as a PCP for sure!

I was very happy with my visit, despite the wait time (which was a result of a very demanding hospital and office schedule). The medical assistant was extremely thorough, and the front desk staff were both professional, courteous and very accommodating. This is a well-run practice and Dr Ast is an accomplished clinician. I look forward to recommending him to family and friends

The whole experience was unbelievably bad. This doctor shares his office with another physician so his name is not even on the door. I had to ask the doorman who directed through a basically unmarked door. The inside was dingy and dark. The receptionist couldn't find my appointment and then it turned out to be the wrong reception desk (there was no indication or explanation why there were two reception desks or which one was for which doctor). The administrative staff were curt and unfriendly. I waited for over an hour to see the doctor even though there did not appear to be many people there. There was no explanation or apology. The doctor was dismissive when I tried to explain the dates of the labs I brought with me. It was like he was reading from a script. When he said his piece and I finally explained the dates on the labs he agreed that blood had to be taken. The person taking the blood was not able to get the blood flowing. It took two of them multiple tries to draw the blood, and eventually the doctor decided that he didn't need one of the tests after all because the blood was too hard to draw. Finally I got out of there. I waited for over a month and did not hear anything about my results so I called the office - again, the receptionist was very rude and just said the doctor would call me back. It turned out they lost my blood - blamed it on the laboratory but at this point I don't even care I would never go back here or recommend this doctor or practice to anyone. It was a complete waste of time and energy and it is astounding that such an unprofessional practice could possibly exist.

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.

I struggle to believe this is a legal, legitimate practice. Both office phones are frequently disconnected or routed to operators. Have not received a call back with my blood work after 3 weeks of trying. Absolutely disgusting, unethical, and likely illegal.

I love Dr. Ast the first time I saw him. Good bedside manner and very informative. However, the second visit was horrible. The office staff failed to notify me that the location I was going to was temporary closed, so I got there and found the door locked. I called the other office location to find out what happened, there was no apology from the person who picked up my call. In fact, she was even a bit insistent that I "must have received a call about the office being closed". She suggested me to go to the other location right away. I did. When I got there, I waited two hours to see Dr. Ast. The front desk again didn't apologize for their lack of communication, barely even looked at me while I was waiting. Worse yet, two months later, I found out they send my blood work to a lab that doesn't take my insurance so I now owe the lab a lot of money! I called Dr. Ast's office thinking that they should be responsible of it. The staff told me "Dr. Ast said he will take care of it". I waited almost two months and it was still not resolved and no one from the office ever got back to me. I really want to like Dr. Ast for his good bedside manner, but all of those issues make it very difficult.

Dr asked a lot of questions, which I totally liked. As a first time patient I didn't feel rushed. I was able to truly and in-depth explain what I've been feeling and going through. He appeared genuinely concerned. I had good vibes from him. We'lo see how the next few visits go. I'm totally optimistic

Doctor Ast had perhaps the best bedside manner of any doctor I've ever had. I normally have a terrible reaction to having blood drawn but he was extremely accommodating and did so in a way that created the least anxiety I've ever had at a doctors office. He also took a surprisingly thorough history and recommended a great podiatrist, too.

I was very disappointed. They were not aware of the apt I'd made through Zoc-Doc and were not prepared for the reason I'd come in. I assume that's also why I waited so long to be seen. Basically, if the provider had reviewed my chart/request prior to the visit I likely wouldn't have had to even gone in- he couldn't help me much. Felt like a waste of time and money. I considered asking to cancel the apt and get my co-pay back, but that seemed futile.
