Forensic Evaluations
Our forensic evaluations provide court-qualified psychological analyses using standardized tools. We assess competency to stand trial, insanity defenses, and mental state at the time of offenses. Our reports help legal professionals understand complex psychological factors in criminal and civil cases. We maintain strict objectivity while delivering findings in accessible language for courtroom settings.

Dr. Williams provides expert testimony in criminal and civil cases with 250+ court qualifications. Our testimony covers psychotherapy ethics, PTSD, malingering, and risk assessment. We explain complex psychological concepts clearly for juries and judges. Our track record includes evaluations for sexually violent predators and fitness-for-duty determinations.
Risk Assessments
We conduct evidence-based risk assessments using validated tools like HCR-20 and Static-99R. Our evaluations measure violence risk, sexual reoffense likelihood, and general recidivism potential. These assessments inform sentencing decisions, parole hearings, and treatment planning. We combine actuarial data with clinical judgment for comprehensive risk profiles.
Psychological Assessments
Our psychological assessments diagnose conditions like PTSD, borderline personality disorder, and malingering. We use MMPI-3 and MCMI-IV testing for objective measurement. These evaluations support civil litigation claims, workers' compensation cases, and licensing board investigations. We identify genuine psychological harm versus exaggerated claims.

Our expertise covers boundary violations, confidentiality breaches, and standard-of-care issues. We analyze therapist-patient relationships and professional conduct.
