The Brain Wellness and Biofeedback Center is one of the industry leaders for research and successful treatment of cognitive and behavioral symptoms, such as concussion, TBI, depression, headaches, PTSD and other debilitating conditions.

We know that each of our clients is unique, having individual histories and differing symptoms. We meet each client with an open mind and no preconceived notions. Each receives an individual evaluation to determine what treatment options will produce the desired outcome. Every client is given an individualized treatment plan. We integrate our plans with ongoing treatments from other healthcare providers. We have an extensive network of physicians and other healthcare professionals that we refer to and partner with to help you find relief from your symptoms.

Can we alleviate all symptoms in everyone? No, of course not, but people come from around the nation to be treated by the staff at BWB based mostly on the word of mouth from others we have successfully helped in the past and from our published research on concussion, TBI and Post-Traumatic Stress.
