Zachary C. Bayer, PsyD grew up in Mary Esther, Florida. After graduating from Fort Walton Beach High School, he completed his bachelor's degree at Auburn University. Following graduation, he worked various jobs in the brain injury community, with adjudicated youth, and in outdoor seasonal adventures. He concluded this phase of life by traveling around the world, visiting 23 different countries in 18 months.  

Dr. Bayer obtained his Masters degree in Psychology at San Diego State University. His thesis focused on early signs of memory impairment and potential Alzheimer's disease in the geriatric population. Dr. Bayer completed his doctoral degree at Pacific University near Portland, Oregon. His dissertation examined the role of coping and executive functioning in individuals with brain injury, as well as their ability to reintegrate successfully into their community.  His predoctoral internship was completed at Mount Sinai Rehabilitation Hospital in New York City - an internationally recognized medical facility- where his training focused on inpatient and outpatient rehabilitation for individuals with neurological injury/illness. The final phase of Dr. Bayer's training was a 2-year post-doctoral fellowship at the Shepherd Center in Atlanta, Georgia- a nationally recognized brain and spinal cord injury rehabilitation hospital.

Dr. Bayer’s decision to return to his hometown and establish a clinical practice was twofold. First, throughout his travels and training, he has long desired to again be close to family. Second, he recognized the significant need for specialized neuropsychological services in the area. Dr. Bayer is excited about practicing in Okaloosa County and becoming an integral part of the mental health and medical community.
