Great PTs, great aides, great environment! I first started at Core Performance with Adam, who was great, but weekdays were too hard for me to schedule, so I started going on Saturdays. I recently concluded about 6 months with the Saturday crew, and they were all terrific! I highly recommend Elizabeth, the PT who has helped me make great strides with my knee. Aides Michael and Darius always had great attitude, as did Lena, who worked the front desk (but is normally a yoga instructor and is super knowledgeable). If you are looking to get your PT done in a relaxed, friendly environment, I suggest Saturdays in Newport Beach!
