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.
-
Everything under 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.

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.

In their own words
What patients say
We love that he rehab’s the brain and we are already seeing so much cognitive improvement.
Every equestrian rider or athlete needs this office part of their team. Especially if you have ever had a concussion or traumatic brain injury!
After 20 sessions I was back to normal and had my memory return and was able to bring my brain out of the sympathetic fight or flight to a calm well balanced state.
My stability is better, and even my sleep has improved in a meaningful way, which has been huge for my recovery.
I feel more in control of my nervous system than ever before.
From my very first visit, he made me feel understood and supported.
Highly recommend this place to anyone looking neuro rehab/recovery. Especially if balance, coordination or the vestibular system has been affected.
It’s one of the most incredible places I have ever been.

Is True Performance a medical doctor’s office?
No. True Performance is a chiropractic- and rehabilitation-led clinic, founded by Dr. Jeff McWhorter, D.C. We coordinate with your physician, who stays responsible for medical diagnosis and treatment.
What happens during the first visit?
Your first visit takes about 90 minutes, plus data and history gathering. It looks at the physical, electrical and chemical aspects of nervous system function, and may include qEEG brain mapping and lab testing.
How is GyroStim different from other balance therapies?
GyroStim uses a computer-controlled, multi-axis rotational chair to combine precise movement with visual, cognitive and sensorimotor tasks. Unlike balance exercises on a stationary surface, the direction, speed and intensity of each rotation can be closely adjusted to your assessment.
How does neurofeedback work?
Sensors on the scalp record electrical brainwave activity and translate it into real-time visual or auditory feedback, so you can practice more regulated patterns during guided sessions. It is non-invasive and does not deliver electrical stimulation to the brain.
