1 - Restore

Phase 1 is to develop a plan to get your life back. Our physical therapy experts will work with you one-on-one to identify the root cause of your pain and create a personalized treatment plan that will reduce your pain quickly, allowing you to continue moving as much as possible.

We’ll also provide you with helpful resources with exercises and pain reduction tips so you can continue to progress even after leaving our clinic. On average our patients see a significant reduction in pain in 2 visits or less!

2 - Reload

You’ve been sidelined by an injury and you’re eager to get back to your old self as soon as possible. Doing less than you’re used to is hard, especially when everyone else seems to be moving on without you.

In Step 2, you’re now doing some activity, but you’re not back to your norm. This is what makes Steady State a different kind of physical therapy - where your goals are at the forefront of the plan. Gone are the days where you're discharged as soon as you start increasing your training.

We help you actually get back to 100% via education, strengthening, mobility, and hands-on techniques - while empowering you with the tools to manage any potential setbacks.

3 - Optimize

You’ve just suffered an injury and the last thing you want to do is go through the pain again. It’s normal to feel concerned that the injury will occur again. In fact, most people worry about this very thing. That’s why our physical therapists make sure that you are equipped with the tools needed to prevent any future injury.

In Phase 3, we help you optimize your body by addressing any long standing weaknesses, range of motion limitations, and training or recovery errors. We encourage you to do more than you've done before - you're finally able to live the life you want!

We’re all runners ourselves & we work with runners across the country who are frustrated with the standard advice of “just stop running.”

A thorough conversation and hands-on clinical exam by our physical therapists is almost always much more helpful than starting with an X-ray or MRI. Orthopedic Physical Therapy before imaging can get you better, quicker while avoiding unnecessary costs, procedures, and long waits for appointments.

I had the pleasure of working with Kelton at Steady State, and I cannot express enough gratitude for the exceptional care and expertise he provided. I am a multi-sport athlete and a back injury was holding me back from being active in the mountains the way I wanted to. Kelton's approach was not only professional but also personalized to address my specific concerns and needs. Through a tailored program, he assisted me in regaining strength and confidence, allowing me to return to all my activities pain-free. The dedication and commitment displayed by Kelton and the team at Steady State truly set them apart. I recommend Steady State to anyone seeking effective, personalized care for musculoskeletal issues.

I ran competitively in high school and college, and got back into running recreationally after a 5-year break. Having decided to commit to a marathon training plan after a few years of running easy without any issues, I encountered a recurrence of knee/IT problems on my left side that had plagued me on and off since high school. I had tried PT a few times without much success, so figured that I would just have to deal with what I assumed to be a structural imbalance. Steady State's philosophy of "keep people active and doing what they want if at all possible" really appealed to me. Working with Brent initially and then Kelton, they isolated the drivers of my ailments (stiff ankles and weak knees/hips) and provided me with strength training to mitigate these weaknesses. This was especially helpful, as — despite embracing stretching to manage injury risk — I had never focused on using strength training as mitigation for injury, and it completely changed my ability to handle the training load I took on. I completed the marathon with a 12-minute personal best, having peaked at 50+ miles per week without any injury issues of note. And while the strength training was the biggest benefit, Kelton provided me with invaluable insights about factors that go into high-performance running — I would have paid for the latter on its own. Looking forward, I will continue to chase goals while having fun, and am indebted to Steady State for the opportunity!

Been working with Kelton since late-2021/early-2022. When I came to him, I believed I would never be able to run long-distance again - my injuries were too strange, the feelings were too esoteric and hard to describe, and everyone else (other PTs included) who I consulted looked at me like I had two heads. Even getting two miles at an easy pace was an event. Some months after working with Kelton, I finished a half marathon. My time was fine, and I was happy I finished (something that was unthinkable when I came to Kelton), but I was discouraged at how hard it felt - my previous injuries did a number on me and I clearly wasn't back to where I was. But I continued working with Kelton, and consistently working through his training plan, and one year later, I came through the halfway mark of a FULL marathon in the same pace as that half marathon - and I continued that pace and faster for much of the remaining marathon. I can't fully express my gratitude and how lucky I am to have found Kelton and the Steady State team. I was truly on the brink of hanging up the spikes for good, but I'm back to doing what I love to do, and will continue to do - injury free - for years to come.

After dealing with a chronic hamstring issue for over two years (along with some misdiagnoses), I serendipitously found myself talking to Kelton in the line to the portapotty before a race in the Whites. I quickly learned he was a PT, and somehow won a raffle for a consultation at Steady State. I was beyond grateful for meeting with him because I was past the point of frustration. From being treated for 'sciatica', 'plantar fasciitis', etc., all of the PTs I was seeing were just completely missing out on the root cause for those symptoms mentioned above. They weren't looking at the whole picture. Kelton quickly determined the cause, and gave me a realistic prognosis with a level of empathy I genuinely appreciate. He's incredibly thorough, timely, responsive, a great communicator and someone I'm glad I can turn to. He didn't beat around the bush and tell me something I wanted to hear. It was realistic, but hopeful. Fast forward a year and some change, and I am the fittest and strongest I have ever been. Training more than I ever have (15+ hours a week), but doing so in a healthy way that isn't detrimental in the short or long term. My hamstring feels great, along with the rest of my body, and finally, I have hope for my future training. The strength training plans and knowledge he passed on to me are going to stick with me. The toolbox he helped create is one I can rely on whenever I need it. Simply put, I wouldn't have made this progress without Kelton. I am forever grateful for meeting him in that smelly portapotty line. I can't recommend Steady State enough. They're simply the best PT related experience I've ever had. THANKS SO MUCH!

Started going to Steady State back in July after experiencing some knee/ankle pain for several months. I had been working with another PT and wasn’t seeing results so I went to SS to get a second opinion. In my first visit I was already feeling more confident that my pain could go away. Dr. Kelton Cullenberg listened to my history and conducted a few tests before providing possible diagnoses and a detailed plan of exercises to help improve these areas. While it’s not typical, I started seeing results right away while still being able to run! After just a couple months of working with Steady State, I am back to running and hiking nearly pain-free. The whole team is very friendly and great to work with! Highly recommend!

I have had a fantastic experience working with the whole team at Steady State. Everyone is kind and responsive and really invested in my success. I started out working with them with a goal to “actively recover” from a marathon. As I train for my next one, it has been so helpful to have the guidance of a PT who is supportive of my goals, has worked with me to create a personalized strength plan, and challenges me to think differently about what it means to train, recover, and stay healthy. So grateful!
