Hi, I’m Sandy Jones. I have been with HSS Rehabilitation and Performance and recently have been given the opportunity to work with HSS P&O, which opened on March 2, 2026. Over the years at HSS, I’ve had the opportunity to learn, grow, and develop professionally, and I’m excited to continue that journey in this new role.

After joining the Rehabilitation and Performance team 10 years ago, I gained priceless experience and built professional relationships that I still value today. Currently, I coordinate scheduling and registration for HSS P&O, ensuring patients receive the vital devices referred by their care teams. Being a part of such a pivotal moment in a patient’s recovery drives me to provide the highest level of customer service every day.
