Doctor of Chiropractic
Your life matters. And feeling better is about more than simply hurting less.
Pain, injury, and chronic health challenges can slowly begin taking pieces of your life away—the ability to exercise, work, sleep well, compete, travel, play with your kids, or simply wake up feeling like yourself.
At Performance Chiropractic, our goal is to help you get those things back.
Regain Your Life. Live Your Purpose.
Dr. Dennis James is a fourth-generation chiropractor with more than 20 years of experience serving Keller and the surrounding Dallas–Fort Worth community. His approach combines decades of clinical experience with gentle, results-driven chiropractic care, Zone Healing, needle-less acupuncture, spinal decompression, shockwave therapy, red and infrared light therapy, and other advanced technologies when appropriate.
But the technology isn’t what makes Performance Chiropractic different.
The person walking through our door does.
We don’t believe in simply chasing symptoms or providing the same treatment to everyone. We want to understand what is keeping you from functioning, healing, and performing at your best—and then create an individualized approach designed to help your body move from limitation toward greater function, health, and performance.
For some patients, that means getting out of pain.
For others, it’s walking comfortably again, returning to the gym or their sport, sleeping through the night, getting back to work, overcoming a stubborn injury, or finding another option after previous approaches haven’t produced the results they hoped for.
And for many, it’s simply getting their life back.
Dr. James has been recognized as a multi-year recipient of the Top 25 Outstanding Doctors of America Pinnacle Award for Excellence in Care. His training includes advanced Zone Healing Technique, Brain and Whiplash Traumatology, health coaching, and fellowship-level acupuncture training through the Acupuncture Society of America.
Yet credentials only tell part of the story.
Results matter. How you’re treated matters. And your experience matters.
That’s why our approach is intentionally gentle, personal, and results-focused. We listen. We evaluate. We explain what we find. We measure progress. And when your situation calls for something outside our expertise, we believe part of excellent healthcare is helping you find the appropriate next step.
Our philosophy is simple:
Heal Better. Feel Better. Perform Better.
Whether you’re experiencing a new injury, struggling with a chronic problem, trying to avoid more invasive options, or simply know your body isn’t functioning the way it should, we’d be honored to discover whether we can help.
You don’t have to settle for simply learning to live with limitations.
You deserve the opportunity to regain your quality of life—and perform through every phase of it.
And after more than two decades of helping people do exactly that, we still confidently say:
“You haven’t tried everything until you’ve tried us.”
Regain your Life. Live your Purpose. Whether you need help getting out of pain, restoring function, overcoming a difficult and chronic condition, or just being able to PERFORM your daily activities as best as you can for as long you can, then we can help! At Performance Chiropractic, we believe your life matters. We believe healing comes from a balanced nervous system, an optimized internal environment, and a body and mind functioning from ease and strength. Now is your time and YOU deserve EXCELLENCE. Having been voted a multi-year award winner for “Top 25 Outstanding Doctors of America” Pinnacle Award for Excellence in Care, a 4th generation Chiropractor, and over 2 decades of experience, we are confident in saying, “you haven’t tried everything unless you’ve tried us!” We look forward to meeting you and discussing the opportunity to enhance your quality of life!
