Meet Your Provider

Hi—I’m Dr. Jonathan Grathwohl, Doctor of Physical Therapy and founder of Proactive Performance Therapy. I help active adults build stronger bones, move with confidence, and perform at their best—so they can keep doing the things they love without pain, fear, or limitations.

​

As a Certified Strength and Conditioning Specialist and Licensed ONERO™ Provider, I specialize in two key areas: helping people with osteopenia or osteoporosis safely rebuild bone density through the evidence-based ONERO™ program, and guiding athletes and active adults to overcome nagging pain or performance plateaus through personalized physical therapy.

​

Over the years, I’ve worked with individuals who want to stay off medication, stay active in sports like golf, tennis, and pickleball, and take a proactive approach to aging well. My goal is to get to the root cause of your issues—not just treat symptoms—so you can move better, feel stronger, and enjoy the freedom that comes with knowing your body can keep up with your lifestyle.

​

At Proactive Performance Therapy, every session is tailored to your goals—whether that’s improving bone strength, recovering from injury, or enhancing athletic performance. I take pride in offering one-on-one, evidence-based care designed to help you stay active, healthy, and confident for the long run.

​

If you’re ready to move beyond pain and take control of your health, I’d be honored to help you get there.
