Dr. Jill Hayes specializes in forensic psychological and neuropsychological assessment and consultation and conducts evaluations in multiple states. Her testimony as a prosecution witness in State v. Jodi Arias was broadcast worldwide and received critical acclaim. The Bureau of Justice Assistance, the U.S. Department of Justice, and various police agencies have sought her expertise.


During her career as a forensic neuropsychologist, Dr. Hayes has conducted hundreds of evaluations for federal and state courts. Examples of prior evaluations for the criminal court system include competency to stand trial, confess, waive the right to counsel, and testify. She also conducts assessments related to mental state at the time of an offense, capital sentencing mitigation, violence risk, sex offender risk assessment, and juvenile transfer to adult court. Dr. Hayes routinely conducts evaluations and/or record reviews in civil court proceedings, including independent psychological and neuropsychological evaluations of plaintiffs with various mental health and substance use difficulties. She also provides evaluations of civil competencies related to guardianship, competency to make treatment decisions, testamentary capacity, and undue influence (retrospectively and prospectively). 

Dr. Hayes also functions as a trial consultant. She explains the practical implications of relevant research to the psycholegal issue, examination findings, and the opinions of other experts. 

In all evaluations, Dr. Hayes strives for accuracy, honesty, and truthfulness. She resists partisan pressures to provide services in misleading or inaccurate ways. She seeks to maintain integrity by examining the issues from all reasonable perspectives and seeks information that will test plausible rival hypotheses. Dr. Hayes utilizes scientifically-grounded practices and procedures. She relies on reliable and valid principles and methods and appropriately applies these to the facts of a case. Consequently, all parties regularly seek her expertise, including prosecution/defense/judges and plaintiffs/defendants.
