Proven Public-Safety Experience
We conduct psychological evaluations for more than 30 private-security firms and law-enforcement organizations, including work involving Securitas, Paragon, Trailboss, Tier One, the Alaska State Legislature, and the Florida Highway Patrol. Our experience includes municipal police, corrections, armed and unarmed security, personal protection, and other safety-sensitive positions.
My advanced postdoctoral training in clinical psychopharmacology and medical psychology also strengthens my ability to consider medication effects, substance use, sleep, neurological issues, medical conditions, and other biological factors that can affect psychological functioning and occupational performance.
Expert Consultation & Legal Matters
Our work also includes consultation involving public-safety fitness, use-of-force issues, personnel matters, and forensic questions. We structure evaluations and reports to withstand professional, administrative, and legal scrutiny.
