"Dr. Haas did a fantastic job, the staff at HSS, and I mean everybody I came in contact with were absolutely were terrific, I can't say enough good things about them."

"I was using a cane and I was certainly worried about my nursing career. I had a knee replacement with Dr. Haas last June and I've been walking, working, and very grateful."

"As a 'young' candidate for a knee replacement at 40 years old in 2000, exhaustive research led me to Dr. Haas at HSS in NYC. The course of my life was forever changed by his talent as a surgeon, sharing of knowledge and most of all, compassion of a magnitude that required nothing less than me paying that same compassion forward. "

"I function now as if I never had knee and hip replacement surgeries. If I have need for any further orthopedic surgery in the future, I will not hesitate to contact Dr. Haas and Dr. Nawabi for their recommendations, and will return to HSS for whatever treatment and procedures I need."
