You wake up stiff. Your shoulders creep toward your ears at your desk. Standing too long makes your back ache. After a long drive, you can barely move normally for the first few minutes.
You've tried massage, chiropractic, stretching routines, physical therapy exercises. Some help for a few days. Then you're right back where you started. You're beginning to wonder if this is just your life now.
Here's what you need to know: None of this is your fault. Your body isn't broken. Something is missing that nobody has looked for, and your muscles are doing exactly what they're supposed to do—they're protecting you. But what if they no longer needed to?
I'm David Quenzer, Doctor of Physical Therapy. I had six years of chronic back pain. Three surgeons recommended spinal surgery, and I almost committed to surgery. But I found another way.
I was doing everything right—what therapists and YouTube said was the best core strengthening, postural training, manual therapy. Nothing worked.
Then I found it—a system that should have been creating stability had gone offline. Once I restored it, everything resolved. No surgery, no ongoing treatment.
That discovery is why I only work with people who've tried everything and gotten nowhere. If that's you, I can help you find what everyone else missed.
Your tight muscles aren't the problem—they're the solution. They're creating stability that should happen automatically. When that system goes offline, your muscles fill the gap. That's why massage and stretching only help temporarily. You're loosening muscles that have no choice but to tighten back up.
Everyone has focused on what hurts. Nobody has asked why.
There are no exercises or stretches you need to do at home. None. This is hands-on work where transformation happens in the room with me. You're not going to fail because you forgot to do your exercises.
You'll feel the difference before you leave. Not because I told you something changed—because you'll feel it yourself. You leave knowing—because you felt it.
Most physical therapy focuses on the muscles that hurt—stretching them, strengthening them, giving you exercises to do at home. I focus on finding what's missing that's forcing those muscles to work overtime in the first place. Once we restore that, your muscles can finally relax on their own.
What this means for you: you stop chasing symptoms and start solving the actual problem. That's the difference between temporary relief and permanent resolution.
You'll feel improvement during your first session. Most clients resolve their issue within 6 weeks. This isn't ongoing maintenance—it's finding and fixing the root cause so you can move on with your life.
Correct. The transformation happens during our time together. You won't get a sheet of exercises to remember. You won't fail because you didn't do your homework. All the real work happens in the room with me.
No referral needed—California allows direct access to physical therapy. This matters because you're not waiting weeks for a doctor's appointment just to get permission to address your pain. You decide you're ready, you schedule, you start.
This is a private-pay practice, and here's why that matters for you: Insurance-based physical therapy can only bill for—and treat—the exact area where you report pain. If your shoulder pain is actually caused by something in your neck or ribcage, they can't go there. If your low back pain originates from your hip or breathing mechanics, they're not allowed to address it.
This is why so many people cycle through traditional PT feeling temporarily better but never actually resolved. The therapist's hands are tied. They can only treat the symptom, not follow the trail to the cause.
By working outside insurance, I can go wherever the problem leads. No billing codes dictating what I'm allowed to find. No 15-minute windows. Just the time and freedom to actually solve what's wrong.
