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.

Dr. Azt seems to be very knowledgeable. He took more time than most of my doctors in talking with me and explaining the tests he wanted to run and what factors he thinks are causing my issues. That being said, the office seems rather disorganized. They were running behind schedule.

I always enjoy my visits to Dr Ast. He is very kind and thorough. The Dr. now shares patients with another Dr specializing in joint pain. Dr Ast seems more relaxed, it's working.

I was the first person in the office this morning when they opened, but I did have to wait about 35 minutes. However, once I saw the doctor I was very pleased. He was very kind, methodical in his questioning, listened to me intently, and thoroughly discussed our plan of action and next steps. I felt very comfortable with him and he wasn't rushed at all - he let me take time to ask all of my questions. This was only my first appointment, but so far so good!

I came to the office for a long overdue annual physical along with a few questions pertaining to recurring upper respiratory infections and trouble sleeping. To address my sleeping concerns, the doctor Googled it for me while I was in the office (while not entirely unhelpful, I could and did do this on my own time) and referred me to the sleep institute across town (those guys were really helpful). When mentioned the recurring upper respiratory infections, the doctor insisted that I should have an allergy test done. I consented, returned later for the test (which was entirely inconclusive), and only afterwards realized that this was an expensive test and not full covered by my insurance. While it is partially my fault that I didn't ask about this upfront, it would have been great to have gotten a heads up from the allergy-specialist doctor that the allergy test he was pushing me to take would be costing me. During my visit for my complete physical, they drew my blood and I began feeling faint (not an uncommon thing to happen as far as I understand). The physician's aid administering the blood-taking process certainly lost his cool and did not know what to do without chasing down the primary doctor to have lie me down and bring me water.

I am a patient for over 6 year. While moving around the city and charging neighborhoods I never look for a replacement. Dr. Ast is an extremely knowledgeable and very accurate with diagnoses he provides. He is also an Astma-allergie specialist so you don't need an allergist either:) You will never feel rushed with Dr. Ast. Your annual check ups will be as detailed and thorough as you never experienced before. AMAZING doctor and very knowledgable team.
