Dr Zelenty is a very caring doctor who spends time with his patients and explains everything clearly and installs full confidence in him. Before i met him, i could not walk more than 100 feet, now I am backing hiking and fly fishing again without issues. He is a miracle worker.

Doctor Zelenty was Exceptional amazing, Brilliant, explaining everything, with a complete package of information from soup to nuts, and I read all three of his phenomenal papers, including the step-by-step that he was going to perform the surgery I think has gone terrific as I will meet with him for a two week check up on July 2. And all I can say is I hope the proof is in the pudding if I'm able to play real real baseball next season in March 2027.

I appreciated that Dr. Zelenty sat down to thoroughly review my MRI with me in a clear and easy to understand way. While he was not able to help me, he was very gracious and made the appropriate referral for further care.

My husband and I did our research and when we came across Dr. Zelenty, we were so impressed, we were willing to travel more than 2 hrs to the hospital as we live down the shore.He exceeded our expectations. His explanations prior to the surgery and post surgery were understandable to us. I am an 80 yr old female and heard stories from different people of this same type of surgery and my recovery time has been beyond what we expected. My recovery has had it's highs and lows but I truly believe with the skills of Dr. Zelenty, that made the difference.

When I was researching physicians for my cervical fusion I used the HSS provider evaluation ratings to narrow down the extensive list of amazing Surgical Rockstars affiliated with #1 rated orthopedic hospital in the USA.
Dr. William Zelenty’s ratings are so extraordinary that I immediately made an online appointment. After spending a long and informative consultation with Dr Zelenty, I had no doubts that I found my Surgical Rockstar and I signed for a terrifying 3 level ACDF.
I’m ten days out from surgery and I’m good!
Dr. Zelenty, Evie and his support staff took excellent care of me and I am eternally grateful for their TLC care.

Dr Zelenty inspired such confidence due to his caring, attentive nature. He personally contacted me several times dues to the imminent blizzard warnings for the area & assured me that his whole team would be there for my procedure. He offered a surgical option that was much better in terms of recuperation & keeping my range of motion.
