ABOUT CONCUSSIONFIX
Real Recovery, Backed By Science - Led By Clinicians Who Understand
Meet the team redefining concussion care through research, experience, and compassion.

Our Story: Born From Experience, Built For You.
We’re three concussion-focused clinicians and researchers who, like many, had to adapt when the pandemic suddenly closed our clinics. But something important happened—we realized that so much of what we do in-person isn’t just hands-on care. It’s education, mindset coaching, and lifestyle guidance rooted in the science of recovery.
We found ourselves having the same deep conversations with every patient—explaining the real root causes of persistent concussion symptoms and how to overcome them. So, we teamed up to create The Concussion Fix: a virtual program that delivers the exact step-by-step process we’ve used to help thousands of patients recover.
Since launching, the Concussion Fix has helped over 4,000 people—many of whom had tried everything—finally get their lives back. Now, we’re here to help you do the same.
