Cabell Williams
Lead Neurofeedback Specialist Virtual Program

Cabell graduated from George Mason University with her Bachelor of Science in Neuroscience and a minor Psychology. She is currently pursuing her Master’s degree in Clinical Research at the University of Virginia. She will graduate in May of 2018.

Cabell is an expert in brain mapping, map analysis and protocol planning, neurofeedback, heart rate variability biofeedback, skin conductance biofeedback, and mirror therapy. If you are a client of our Virtual Program, she is the expert who will conduct your initial brain map and assessment session; a process that can take 2-3 hours of dedicated analysis.

When not working at Peak Neurofitness, Cabell is conducting research on the biomarkers for social engagement in infants using EEG and fMRI technology at the University of Virginia.

Cabell has also worked at George Mason’s Youth Emotion Lab, where she studied the effects of stress on parent-teen interactions and how it can lead to delinquency, substance abuse, and educational issues later in the teen’s life. Her work there entailed administering Heart Rate Variability Tests, collecting cortisol samples, genetics testing, and drug testing. She also administered psychiatric diagnostic testing, stress tests, and risk assessments for suicide, self-harm, and child abuse.

Cabell currently lives in Charlottesville, Virginia with her loving dog, Moon. She enjoys mindfulness practices, backpacking, cooking, working out, and socializing.
