After meeting John and working with him after one month of rehabilitation I had no doubts that he would help me get back to my best. The best physical therapist out there!

The doubts I hear most

Still on the fence? Good.
Let's talk about it.

These are the four questions people ask me most. Here's how my clients answered them.

Doubt 01“Is it worth the investment?”

Fair question — and the most common one. But run the other math too. What's another six months of “stuck” costing you? The season. The slopes. Your job. Your confidence in your own leg.

Eli wasn't working when we started. He found a way to invest in his knee anyway — because he knew it was the fastest way back to work. Today he's hiking, running, surfing, and playing soccer.

Kevin · Back to law enforcement & basketball
“His focus was never on the billing cycle; it was entirely on getting our daughter healthy.”
The Peboontom family · Karina made varsity
“Don't waste your time with non-experts. I wish I worked with you sooner.”
Kendra · Hiking, biking & running again
Doubt 02“Will online actually work for me?”

ACL recovery comes down to progressive loading, movement quality, and measuring progress. All of that coaches extremely well over video — with eyes on your movement every week and a plan that adapts.

Flavio did his rehab 100% online and straightened his knee for the first time since surgery in 2 weeks. Anthea went from 88° to 121° in four months — online. And Eli asks this exact question near the end of his video.

Doubt 03“How can you help if you can't touch my knee?”

Most of what rebuilds a knee after ACL surgery isn't hands-on. It's the right exercise, at the right dose, at the right time — and proving it's working.

So we measure everything. You film, I review: knee straightening and bend, quad strength, swelling, landing and cutting mechanics. Then I adjust your plan — every week. Nothing gets missed because nothing goes unmeasured.

Doubt 04“I feel bad leaving my PT.”

You don't have to leave. Kevin kept his in-person PT — we worked together, and he finally got the push he was missing. He's back on the job and on the court.

Some clients do both. Some decide working with only the ACLRx team is right for them. Either way, you're allowed to get what your knee needs. We'll figure out the right fit together on your call.

Client message: I wouldn't have made this much progress with physical therapy alone.

“8 months out, still going to PT, told to trust the process.”

That was Jean. Missing motion, knee pain, no confidence in his leg. Today he's dunking.

John is a wonderful physical therapist who has extensive knowledge about any knee injuries one may obtain… He pushes you to your limit without hurting yourself… I highly recommend John to anyone with an ACL or knee injury, as you will feel like it was never hurt in the first place.

My daughter had just had her second knee surgery and needed intense PT. John immediately set a plan for her and was extremely supportive and understanding to all of her needs, concerns and challenges… The results came daily and weekly as she gained strength and confidence.

I've seen a few physical therapists over the years, but John is the first to really make a huge difference in my recovery… I must have asked him a million times to explain why something was happening, and he always did.

I had the pleasure of working with John after my ACL injury from a skiing accident. John's knowledge, reassurance and patience got me back on a slope the following season… If it wasn't for him I don't think I would ski again.
