Griffin Psychological Services, LLC was founded by Michael P. Griffin, Ph.D. in 2008, and is based in Raleigh/Durham, North Carolina. GPS was founded on the principles of providing legal clients objective, thorough and concise work products while similarly offering therapy clients a safe and personalized experience. While services are regularly offered in North Carolina, Virginia, and Alabama, clients from other states are accepted on a case-by-case basis.

Desirée Griffin, Ph.D.

Desirée earned her Ph.D. in clinical psychology in 2011 from The University of Alabama after having received a coveted Presidential Scholarship – effectively paying her undergraduate tuition, in addition to myriad other scholarships and awards (e.g. McNair Scholarship and J.L. Bedsole Scholarship) based largely on her exceptional performance. In fulfillment of her doctoral work, Desirée completed an APA-approved, clinical internship in the University of North Carolina – Chapel Hill, Department of Psychiatry, with a major rotation at the Federal Correctional Complex in Butner, North Carolina. She then served as a psychology resident at the Southern Virginia Mental Health Institute (2011 – 2012) for a postdoctoral fellowship where her responsibilities ranged from completing forensic evaluations to serving on treatment teams and conducting individual therapy. Since July 2012, Desirée has served as a Lecturer in the psychology department at the University of North Carolina – Chapel Hill. This move allowed her to simultaneously pursue her two passions (teaching and clinical work), thus she joined GPS, applied for independent licensure, and recently became a licensed psychologist.

GPS provides a range of forensic and patient-focused services. Forensic services offered by GPS range include forensic evaluations, fact testimony, jury selection, witness preparation, case conceptualization, and optimization of trial presentation systems. Forensic psychological work is an ever-changing endeavor depending on the type of trial, the trial dynamics, the circumstances of the case, and human factors (e.g. the impact of the judge, jurors, attorneys, witnesses, clients, and other courtroom personnel). Please explore the information provided on each of the highlighted services by clicking the associated links.

Patient-focused services offered by GPS include individual and couples therapy, as well as limited clinical evaluations. This type of work is taken on a case-by-case basis due to the notable impact personality dynamics between therapist and client have on therapeutic success.

Forensic Services

Case Conceptualization

Determining how to approach a case, whether civil or criminal, has a significant impact on the outcome of the proceedings. Moreover, attorneys working on a case often form very strong opinions early-on in the process based on past cases they have tried and personal biases. However, no two cases are exactly alike, and it is worthwhile to consider psychological variables that may inform case-relevant facts (e.g. the impact a defendant’s substance use may have in understanding the offense) or impact jury decision making. Case conceptualization, much like an actual trial, is a dynamic process where input is constantly being considered and discussed to develop a fair understanding of the facts.

Fact Testimony

The nuances of forensic psychology are difficult for many people to grasp. The range of clinical, forensic, and research roles of forensic psychologists can be confusing — even within the realm of psychology — and attorneys, judges, and jurors are no different. Court cases often benefit from a direct, factual, and unbiased explanation of forensic issues.

Forensic Evaluations

GPS conducts a wide-range of criminal and civil forensic evaluations on plaintiffs/defendants (as requested by either party). These evaluations include (but are not limited to) mental state at time of the offense, competency/capacity to stand trial, future risk, mitigation, disability determination/worker compensation, future risk, intellectual functioning (for Atkin’s cases), etc. In addition, clinical evaluations (e.g. clinical interviews and psychological testing) are available for attorneys who simply wish to discover whether their clients have developmental delays or other psychological issues not for direct use in trial as such information may assist in the resolution of the case.

Jury Selection

Psychologists are specialized in understanding human attitudes, behavior, and emotions. Throughout the course of a trial, jurors are exposed to information that shapes their attitudes about the defendant. While the task of jury selection can often be construed as a whirlwind of questioning and the arbitrary dismissal of potential jurors, GPS provides an informed, research based approach to jury selection based on sound psychological variables as such, the jury selection process leads attorneys to be more confident in the ultimate jury panel.

Trial Presentation Systems

Most professionals have not been trained to effectively implement visual aids or maximize their utility. We have performed a thorough review of the relevant research and conducted multiple studies to test the usefulness of presentation software. These investigations have led to a series of principles which will greatly help in the preparation of your presentation or testimony. While we primarily provide detailed feedback on the visual presentations you have already prepared and offer suggestions on how to vary your use of available technologies, we also are able to assist in preparation of materials.

Witness Preparation

People are often unaware of how others perceive them. Even the most accomplished of people can be wholly incapable of relaying information or coming across in a way consistent with their personality and intentions. More importantly, people who are able to present themselves accurately often buckle under the pressures inherent in a trial environment and make costly mistakes. GPS witness preparation helps people to provide a true representation of who they are and best communicate the information they have been asked to offer the court.

Individual Services

Individuals/Couples Therapy

Therapy clients are considered on a case-by-case basis and are interviewed to determine if there is an appropriate fit between the client’s needs and therapist expertise. Personality dynamics are also considered and discussed to conclude whether therapy will progress. Once treatment has begun, we implement Evidence-Based Therapies to assist you in reaching your treatment goals. If requesting couples therapy, neither party can already be receiving individual therapy from the GPS provider.

Clinical Evaluations (patient-centered)

GPS occasionally conducts clinical evaluations for established patients or referred individuals. These evaluations are typically used by individuals interested in personal growth, job search/satisfaction, or intellectual curiosity; however, the results can also be used as future documentation of intellectual and/or cognitive functioning, personality structure, psychiatric symptoms, etc. Developmental (e.g. assessment for Pervasive Developmental Disorders, as well as gifted and/or special needs) and neuropsychological conditions assessments are not offered by GPS at the present time.
