Clinical Forensic Psychology

Clinical Forensic Psychology is an area of specialized practice in which clinical psychologists provide services to address, and at times clarify, aspects of a legal question or issue in either civil or criminal cases. Clinical forensic psychologists provide evaluation or treatment services to individuals and/or families. They also provide consultation services to attorneys and courts.

Forensic psychological evaluation is a complex process that involves extensive interviewing, collection of collateral information, review of relevant records and psychological testing. Some forensic consultations can be less extensive and focused on limited aspects of a referral question. Opinions regarding forensic cases cannot be offered unless a professional relationship has been established beforehand. Such a relationship is typically arranged with Dr. Marshall by an attorney.
