Physical therapy, strength training, and consultation services to dedicated runners and providers looking to master running injury management and performance.




Physical Therapy

There’s nothing worse than not being able to run. Let me help you get back to being yourself!

Whether you are dealing with a tendinopathy, bone stress injury, or other complaint, I am to offer a world-class rehab experience to endurance athletes of the Midwest. I combine the latest research in running-related injuries with my 12 years of experience working with runners of all ability levels. This process begins with getting a good understanding of you. I’ll analyze your unique training history, medical history, and life experiences to understand what brought you to my door. Second, I’ll perform a comprehensive orthopedic evaluation focused on the specific performance demands of running. Lastly, I’ll watch you run. A detailed biomechanical running analysis is necessary to determine if we need to modify your running to best manage your current state. I’ll distill all that information into a simple, actionable plan for you to complete moving forward.

If you’re ready to get back to running at 100%, schedule a free 15-minute phone call below.

Bone Stress Injury Rehab

Bone stress injuries (stress reactions, stress fractures, and full fractures) are the most challenging injuries runners face. I teach both nationally and internationally on the diagnosis, management, and prevention of bone stress injuries. This specific diagnosis requires a tailored approach both to the assessment and treatment. I’ve developed my approach to managing these based on my current understanding of the literature and over a decade of practice managing these injuries in elite professionals to everyday joggers.

If you’re looking for world-class management of your bone stress injury (BSI), book a 15 minute phone call below.

Strength Training

Resistance training is one of the most helpful elements a runner can add to their training. But it can be a struggle to figure out what to do, when to do it, and how to incorporate that into a busy schedule and life. Your strength routine should be individualized to you and include fundamental movements, a steady dose of single-leg exercises, and specific loading to the areas that work a lot when you run.

Over the last decade, I’ve been lucky to write strength training plans for:

“Nathan has been an asset to many of our athletes, especially those with the most complex injuries.”

I was referred to Nathan as a senior in high school for the continuation of physical therapy and further strength training after having surgery for a navicular stress fracture. Nathan was invaluable in my return to racing with his extensive work with runners, knowledge of running injuries, rehab and injury prevention. I was able to have a successful senior track season and continue setting PRs at Oklahoma State where I have since become an All-American in cross country. I have continued working with Nathan for strength training every opportunity I can in the summer and winter breaks when I am home from school. He is flexible with my schedule and easy to reach via text or call. Since working with Nathan I feel stronger, healthier and less injury prone.
