An expert witness is qualified by their specialized knowledge, skill, experience, training and/or education to testify in the form of an opinion. Psychologists testify as experts in a wide variety of circumstances. These psychologists are engaged in Forensic Psychology. According to the American Board of Forensic Psychology (ABFP), the definition of forensic psychology "is the application of the science and profession of psychology to questions and issues relating to law and the legal system."

Why Our Forensic Psychologists?

First consider, “What do forensic psychologists do?” They apply the science and profession of psychology to questions and issues relating to law and the legal system. We believe this requires specialization in forensic psychology. Requirements attained by our psychologists include knowledge, experience and training in psychology and legal issues.

Lower Expert Witness Fees

In accordance with the APA Specialty Guidelines for Forensic Psychology, we will keep you informed of new information, opinions or other potentially relevant information as it arises. Based on our initial screening, you may terminate our engagement without falling subject to payment of the subsequent fees involved in the forensic assessment process.

Less Surprises During Expert Witness Testimony

We prepare our reports in anticipation of testimony. Therefore, we rest our opinions upon generally accepted, scientific, reliable and valid forensic psychological evaluation methods. Our reports factor in corroboration, collateral information, alternative hypotheses and limitations. Our method is reasonable, comprehensive and transparent.
