The team at JROP is amazing - everyone is very friendly and their providers are really motivated to get you out of pain! They were able to help me avoid a knee replacement and were also extremely informative every step of the way. I would recommend to anyone with knee pain to come in and see them for a consultation!

This has been life changing for me. I have a much easier time walking and being active now. I've done a lot of injections in the past but nothing with results like this. I cant recommend them enough if you have knee problems or joint pain.
