As a result of months of isolation in this pandemic, my husband and I had our physical conditions (ACL surgery and sarcopenia) worsened. The therapists at the clinic on 4th Street, with patience and dedication, managed to get this old east villager couple back on track. We are grateful for their... excellent work. Great clinic. Great more

Nathalie and the staff are thoughtful, attentive and professional. They have me doing exercises that are difficult to do by myself and have taken lots of time teaching me to do them correctly. I am very confident that my shoulders will be back to normal soon. I highly recommend ProPT.
