Sports Medicine Clinic in Rancho Santa Fe, CA
Rebuild the Brain. Raise the Ceiling.
Concussion recovery, brain injury and stroke rehabilitation, and sports performance work under one roof. Care is chiropractic- and rehabilitation-led, and coordinated with your physician.
The difference
Why patients travel to Rancho Santa Fe for this work
Patients travel from outside Southern California for Dr. Jeff McWhorter's approach. Four things set the clinic apart, and each one is something you can check.
-
One roof
Vestibular and eye-movement work, GyroStim, neurofeedback and hyperbaric oxygen run inside one concussion program, planned from one evaluation instead of four separate referrals.
-
GyroStim, in house
A computer-controlled, multi-axis rotational chair that challenges balance, processing speed and coordination. We are listed in the official GyroStim provider directory: the only Southern California listing (September 2026).
-
Hyperbaric, in house
A pressurized monoplace chamber on site. Sessions typically last about 60 minutes, and hyperbaric oxygen joins a plan only when it fits your findings and goals.
-
Pro sideline
Before founding True Performance in Rancho Santa Fe, Dr. McWhorter served as a chiropractic consultant to the Denver Broncos, working with elite athletes to improve recovery and performance.

“Working with Dr. Jeff McWhorter has taken my game to the next level, especially when it comes to awareness, reaction time, and coordination.”

What's up guys, Christian McCaffrey here. I've been coming in working with Dr. McWhorter for the last, I don't know how long, last few years, and I gotta say it's taken my game to the next level, as far as awareness in space, being able to react, and coordination in general. Syncing this in with all my training stuff has really helped me, and working with him, always pushing the limit, always taking us to a higher level. So very thankful for the work that I get to do with him, and I would encourage anyone who wants to get better, the training aspect or just healthier, as far as brain development in general, to come in and see him.

“We are seeing Dr. Jeff because my husband had a stroke. We love that he rehab's the brain and we are already seeing so much cognitive improvement. He has only had 7 sessions and we can't wait to see the results. We feel like he is the piece of the puzzle we have been missing and wish we would have known about him a few years ago. We are already telling everyone we know that we feel could benefit from his services.”
“Every equestrian rider or athlete needs this office part of their team. Especially if you have ever had a concussion or traumatic brain injury! They have significantly improved my overall brain performance for riding horses, playing golf, and running a business.”
“I started here with Neuro feedback after a surgery left me stuck up in high gear(sympathetic nervous system response)I had little ability to retain information and had forgotten much of the previous year including some friends. … I’d recommend this location and its functions for anyone suffering from something similar.”
“Highly recommend this place to anyone looking neuro rehab/recovery. Especially if balance, coordination or the vestibular system has been affected. … The staff is really great - in it for the right reasons and passionate about helping people. Very competent as well.”
“This place is so incredible. I don’t even know where to start the staff. Every single one of them is top-notch and cares a great deal about me, taking care of me every visit with very detailed and precise treatment. … I came in here with massive anxiety and it’s been three weeks of work, but I am already turning the corner and feeling better.”
“What really sets True Performance apart is the staff. Every single person I worked with was not only extremely knowledgeable, but also genuinely compassionate. They took the time to understand what I was going through and made me feel supported every step of the way.”
