"I have been experiencing knee pain for about 3-4 years now as a Highschool athlete which is something that really sets back people in their daily lives and on the track. At some times I would be limping at practice or it would hurt to even get up out of a chair. Po-An Tsai really helped me clear this all and explode as an athlete through his program. I don't have knee pain holding me back like it did in the past. I truly recommend this program if you wish to relieve yourself of any type of knee pain."

"I can't thank Dr Po-An enough for the progress I've made since mid-November 2025. We've been focusing on the pistol squat, and he's been great helping me build real strength. While I haven't reached the full pistol squat yet, the progress is undeniable. I've gained significant strength in my ankles, knees, and core. I highly recommend this clinic for anyone looking for goal-oriented, physical therapy."

"I can't recommend Po-An Tsai and this program enough! I joined because I was dealing with persistent knee pain whenever I ran, and after completing the 12-week program my knee is completely pain-free when I run."

"I went in with ongoing knee pain and had an exceptional experience with Po-An Tsai. From the very first session, he was incredibly warm, knowledgeable, and attentive. He took the time to truly listen, explain the root of the issue clearly, and tailor the treatment specifically to my needs. The exercises and guidance he provided made a noticeable difference, and over time I saw real improvement in both strength and mobility. I now feel far more confident in my movement. I'm genuinely grateful for his care and would highly recommend him to anyone looking for an excellent physiotherapist."
