What Our Clients Are Saying
-
"I am an avid disc golfer and hurt my back really badly playing. I couldnt sit for more than a minute for 6 months. Chiropractors only hurt me worse. I called many places with no call backs. I called Flex line and he was at my house the next day. After just 1 visit i was 90% out of pain. He gave me weekly exercises to do until our next visit. We found the root cause and knocked it out. I would highly highly recommend."

"I had severe back pain for almost 7 months. After just 6 weeks of working with Flexline using dry needling and PT, I have no pain with movement or pressure on my spine! Tim provided incredibly well-informed care and education and provided in-depth support. He was very knowledgeable about human anatomy which allowed him to properly treat my symptoms and discover contributing factors to my pain that my other doctors and trainers had missed."

Frequently Asked Questions
Have questions about treatment, insurance, or what to expect? We've got answers.
-
No referral needed! Texas is a direct access state, meaning you can come straight to us without seeing a physician first. If we determine you need a referral for further medical management, we'll guide you in the right direction.
-
It depends on your condition, goals, and how your body responds to treatment. After your initial evaluation, we'll outline a clear plan based on your specific situation. Some clients see significant improvement in just a few weeks, while others may benefit from ongoing sessions to build strength and prevent re-injury. We'll make sure your plan is tailored to you.
-
Come dressed to move! Your first session is a full hour dedicated entirely to you. We'll take time to hear your story, understand your goals, and assess how your body moves—not just where it hurts. We use tools like VALD ForceDecks and Dynamo to gather real data and take the guesswork out. By looking at how everything works together, we build a personalized game plan to help you move better, feel stronger, and stay pain-free. Most of the time, we'll begin treatment during that first visit.
-
We're a cash-based practice, which means we don't work directly with insurance companies. This allows us to spend more time with you—every session is one-on-one with a Doctor of Physical Therapy, with no insurance restrictions on treatment. That said, physical therapy is a qualified medical expense, so you can absolutely use your Health Savings Account (HSA) or Flexible Spending Account (FSA) to cover your sessions.
