Helping active and driven people return to pain-free performance on the bike and on the trail.
Your choice provider for returning to fearless movement. Located in Prescott, AZ, and available for online consults and programming worldwide.
Forged in science, grounded in movement.
I offer Physical Therapy and performance services for those who want to move better, get stronger, leave their injuries in the past, and get back to doing the things they love.
Have you tried physical therapy in the past, only to be disappointed? Were you given a few exercises and stretches, but felt like you only ever got back to 80%? Did you wish you got to spend more time with your therapist, instead of techs or aids? You are not alone; I have helped many people who tried physical therapy before without getting the outcomes they wanted. Book a discovery call or visit to discuss how Chain Reaction Physical Therapy is different and how we can help you achieve significant and long-term results.
Pain is a symptom, not a cause.
Injury and pain are often due to movement patterns that have evolved over a long period of time. My goal is to help find the reason behind your pain, and in doing so, treat the symptoms.
Services
-
Physical Therapy
In-person Physical Therapy with a focus on helping you return to pain-free, confident movement by addressing pain, imbalances, and strength.
I specialize in working with cyclists and trail runners, and offer a personalized, athlete-centered treatment approach.
-
Bike Fits
In-Person and virtual options available.
I offer two-hour bike fits that evaluate your body, biomechanics, and how you interact with the bike, assessing everything from posture and joint mobility to cleat positioning and saddle size. A proper fit means more comfort, better power, and fewer aches so you can focus on the ride, not the pain.

Self-Paced Strength Programming for Cyclists
An instant-access program for cyclists who want to get started with strength training and get real results without sacrificing ride time. If you’re a cyclist who hates strength training, this is for you.
Each session runs about 40 minutes, two to three times a week, with every exercise chosen to make you stronger and more resilient on the bike, not just in the gym.
-
Clinician Consultations
I offer one-on-one mentorship sessions for physical therapists who want sharper clinical reasoning, more confidence with complex cases, or real-world guidance on building and running a private practice.
Each 60-minute session is built entirely around what you need most. There no preset agenda, no generic advice, just practical strategy you can put to work immediately.
You've put thousands of miles into your legs. But repetitive movement without addressing what's underneath it is how small imbalances become big injuries… and big injuries become time off the bike.
Let’s keep you riding for the long haul.
