Dr. Ast was wonderful. He clearly explained my hip problem so that I understood my choices and options. We discussed the pros and cons of a hip replacement which he clearly articulated the risks and benefits. He gave me confidence in his approach to a hip replacement. I made the decision to move forward with the replacment as a result.

My confidence in Dr. Ast is evident, lol. I had my left hip done with him in December, and I returned to him in April to have my right hip done. I pretty sure that shows how confident I am in Dr. Ast and the HSS team.

I came to HSS after my ortho stopped doing knee surgeries and I did not care for docs he referred me to - who were very brash, cocky and mechanical. Dr Ast speaks straight, but he also explains things so my husband and I could understand how to prep, what to expect during/after surgery, etc. I made the absolute right choice in selecting Dr Ast, and couldn't be more thankful for the outcome of both surgeries (2 knees, 5 mos apart) and grateful to Dr Ast and his HSS staff.

Overall one of the best health care experiences I’ve had!

I couldn't have chosen a better surgeon. He gave me my life back-well at least half of it. Im scheduled for surgery in another four weeks, four months after the first hip replacement surgery. I'm looking forward to it. That should be an indication of how confident I feel with Doctor Ast as my surgeon. I highly recommend him.

I cannot say enough good things about my entire care team - so much so, I'm going ahead now with second knee surgery. From the receptionists to the nurses and docs, to PT, xray techs, and all the supporting medical personnel who answer portal questions I sent to Dr Ast's office in a very timely manner, I have found everyone to be exceptionally professional and helpful.

HSS, Dr. Ast, and every employee I have encountered has been exceptional. I highly recommend HSS and have referred friends and family. Thank you

Dr. Ast has a wonderful bedside manner. He listened carefully to my concerns, conducted a thorough examination and shared his evaluation with me. He concluded that I do not need knee surgery but rather the issue is coming from my lower back. His examination included simple tests that support his opinion (tests another doctor at a different hospital did not do and his treatment options would not address the issue in my back). I left Dr. Ast’s office impressed with the facility, the staff and Dr. Ast!

Dr. Ast truly made me feel like I had chosen the right surgeon. He smiled, made eye contact, asked repeatedly if I had any further questions, and actually made me laugh with his smiley face signature on my knee...much needed and appreciated! :-)
