Post-Concussion Syndrome

“Dr. Titus has been a lifesaver for me. In 2006, I had a serious traumatic brain injury. Upon getting started with Dr. Chiu, I was immediately comforted by his full engagement to eliminating my headaches. He listens, he educates, and most importantly, he puts you in the driver’s seat for your health. For once, I’m actually not losing 2 or 3 entire days per month to migraines. Dr. Titus has unquestionably made this possible for me”
