Patient Testimonials
“I had a great experience with Park Sports PT while rehabilitating from a wrist fracture of my dominant hand. I don’t believe I ever waited more than a minute or two to start a session. The exercises prescribed and the modalities used in each session were effective and creative when modifications were needed.
Allison, my OT, had a great personality and was very caring to all her patients. She seemed to remember even the most insignificant details I had shared and would ask me follow up questions. Impressive! I can only speak for myself, but I truly think all of the patients I shared time and space with in the cozy communal upper extremity corner of their gym like office in the South Slope were equally impressed with the expert care doled out to everyone who walked in the door, no matter what their injury or limitations.
Allison Sanchez-Masi, I will forever be grateful for how you helped me get to the other side of a challenging situation. I’m as good as new and I have you to thank for my successful rehabilitation.”

“I have been going to Park Sports off and on for five years (injuries/surgery). Right now I am in pt as a result of major hand surgery. I am working with the owner, Boris Gilzon…whose specialty is the hand, and I was treated there last week for one and a half hours so no one can say they rush you! They treat me with new methods every time I go and my hand really does feel soothed after therapy.”

“Allison Sanchez-Masi is a wonderful hand therapist at PSPT, working mostly out of the 6th Av site. After rupturing a ligament in my thumb, which had me terrified b/c I’m a writer (a/k/a full-time keyboard operator), Allison helped me get back to normal lickety-split. And like all great PTs, her energy is a huge component of the healing process. Her warmth, care, and patient encouragement really helped me re-orient how i was dealing with the process of recovery. it’s not about an injury: it’s about healing.”
