Athletes who got their sport back
Pro and youth athletes who tore an ACL, blew out a knee, or got hurt — and trusted us to get them back.
"Zack was the only person I met pre-surgery who gave me an outline of my next few months based on how I was performing — not just how many weeks it had been since surgery. I'm 6 months out and most of my test numbers already look better than before my injury. I'd 100% recommend Primal to any athlete going through ACL rehab."
"Zack provides one of the most advanced yet highly individualized physical therapy. His use of technology, personal experience, and knowledge gave me the best possible care after my ACL surgery. He listens, he cares, and he goes above and beyond. Without his expertise, I would not be back to playing soccer at a high competitive level."
"I came to Zack months after my ACL and meniscus repair with multiple problems and a lot of pain. His deep knowledge and personalized plan are the sole reason I'm finally back to my normal self — he even helped me realize I needed another surgery. I'd lost hope my knee would ever feel normal again. Zack proved otherwise. There is no better option for your recovery."
"Dr. Nolff is one of the most knowledgeable people I've ever interacted with. He dedicated his valuable time to help me recover from my ACL injury."
"Primal actually fixes the problem instead of slapping a bandaid on it. After 8 years of hamstring issues, just 2 months with Zack and they're stronger than ever — no more pain. Going into my 5th NWSL season, I've never felt more confident in my body."
"I've worked with Zack for 5 years now. He's incredibly knowledgeable about keeping players healthy and rehabbing injuries, using functional movement specific to your sport. He truly listens to the athlete to build the best plan possible."
"Zack is amazing! I spent several weeks with him during my offseason and it was a joy. I'm feeling fit, strong, and ready for the upcoming season. He's the best — highly recommend!"
"Zack is extremely knowledgeable and so helpful with my recovery and injury prevention over the off-season. Flexible with my schedule and consistently checking in on my progress. I'd highly recommend him to anyone, especially in the soccer world."
"Zack was awesome helping me rehab my ankle sprain. His soccer-specific techniques were exceptional — tailoring the rehab to real soccer movements made a huge difference in both my recovery and my performance on the field."
"As a professional athlete, being injured affects my lifestyle and my job. I had a calf injury weeks before a tournament and couldn't train without pain. I messaged Zack, got an appointment immediately, saw results right away, and have had no calf pain since. Extremely dedicated, professional, and personable."
"Great ACL rehab — these guys are amazing."
An ACL tear is bigger than one season
This isn't just a knee. It's your kid's confidence, their identity, and their future in the sport they love. And here's the hard truth: the rehab path you pick now decides how this story ends.
Most clinics rush athletes back or guess when they're "ready." That guess is exactly how second tears happen. We refuse to work that way.
- More time on the sidelinesThe wrong plan drags a 9-month comeback into a year-plus.
- Money down the drainShort, shared visits that never actually move the needle.
- A far higher chance of re-tearingGoing back too early is the #1 reason ACLs tear a second time.
- An athlete who loses their nerveFear of re-injury holds them back long after the knee heals.
Four steps from surgery to your sport
No more wondering if you're doing the right thing. The program blends one-on-one care with semi-private coaching, so you always know exactly where you are and what comes next.
Reset
Calm the pain and swelling, get your knee bending and straightening like it should, and lay a solid base to build on.
Rebuild
Make the knee, hip, and ankle strong again with training built around your sport — not a generic sheet of exercises.
React
Train speed, balance, and control so your body reacts the right way under pressure. This is the work that protects you from a second tear.
Return
Prep for the real demands of your sport — running, cutting, jumping, sprinting, contact — so you walk back on the field without a shred of doubt.
We measure it. We don't guess it.
Most clinics clear athletes "by feel." Think about that for a second — your kid's knee, cleared on a hunch. We use the same tools the pros get tested on to measure strength and movement in both legs, side by side.
If the hurt leg isn't as strong as the good one, you're not ready — full stop. And the numbers tell us the exact day you are.
- Force plates that measure how hard each leg actually pushes
- Strength testing that pits your hurt leg against your healthy one
- Movement screens that catch risky habits before they cause a re-tear
Why this matters
Real targets, tracked every step — so you and your family can see the progress on a screen, not just hope for it.
ACL and everything around it
An ACL rarely tears alone. We handle the whole knee — and every joint that has to carry it.
