My experience with Dr. Downing was very positive. His credentials speak for themselves. and his commitment to his profession is apparent upon first meeting. I have complete faith and trust in him and his expertise. All my questions and concerns were addressed every step of the way and his staff is very accommodating and knowledgeable. My recovery has been amazing Thanks to Dr Downing ,his staff and Mercy Hospital.
in Hamburg, NY |
I had a triple bypass in March 2017. My surgery went flawlessly, and because Dr. Downing and his staff clearly explained the procedure and what to expect after, there were no surprises for me or my family. I followed all of the rules and recommendations laid out by Dr. Downing and his staff during recovery, and it has resulted, so far, in a quick and easy recuperation. I could not be happier with the care I've received before, during, and after surgery.

in Derby, NY |
I met with Dr. Downing prior to my surgery and found him to be very personable, informative and very reassuring. He took the time to explain exactly what my surgery would involve and how I might feel afterwards. He also made me feel more at ease with the procedure he explained. After leaving his office, I definitely was a little less apprehensive.
in West Seneca, NY |
Dr Downing was very professional and friendly. He explained everything adequately and answered all our questions. The follow up after surgery was positive. I would highly recommend Dr Downing to anyone that has need for a lung surgeon.
in Buffalo, NY |
Dr. Downing and his entire staff performed above and beyond all of my expectations. They spent a great deal of time with my wife and myself discussing my options regarding my surgery. Even with complications shortly after surgery, the Dr. and his entire staff where able to save my life. I can now move on to a normal life after a short recovery period. I owe my life to Dr. Downing and his entire staff.
in Sinclairville, NY |
Dr. Downing and his staff were wonderful. They are very professional and we thank them so much. We would highly recommend this doctor.
in Hamburg, NY |
My experience with Dr. Downing & his staff was fantastic!!. I specifically want to recognize The P.A. Brian. He is truly an asset to Dr. Downing & probably doesn't get enough recognizition for what he does
in Niagara Falls, NY |
After major surgery times 2, Dr. Downing saw me only once in more than 60 days and that was when he was making rounds with staff. No questions were asked of me, no information of my condition was given to me. Dr Downings comments were all directed to those making rounds with him. While in rehab a require appointment was scheduled well in advance when I went for the appointment Dr Downing wasn't in office and I was seen by an underling. He may be rated good but his treatment of me was poor.
