About Us

Our practice specializes in neuropsychological and forensic evaluations. We opened our doors in 2015 with the vision to change the landscape of forensic mental health service delivery. We approach our evaluation services by working collaboratively with our clients while embodying care, responsiveness, and excellence. In our evaluations, we examine links between the brain and behavior. The understanding of how you think, act, and how the brain works is what we use to diagnose a brain disorder. We will assess how problems with the brain may relate to problems at home, school, work, or with the law.


To change the landscape of forensic mental health service delivery, improving quality of life, and promoting safer communities.


To provide excellent services to our clients through the use of top-of-the-line standardized testing instruments, evidence-based research, and comprehensive reports.
