Areas of Professional Practice

Complex Psychological Evaluations


In the office, hospital, or jail our team works together to conduct evaluations in medico-legal and other complex-system settings.  


We strive for impartiality that is not influenced by the referral source or the source of funding. Contact us about your evaluation need, and we'll send you our usual "agreement letter." Then we'll get started.

Medical Psychology and Neuropsychology


Medical psychology and neuropsychology share with the fields of health psychology, behavioral medicine, and neuroscience, an interest in the ways in which biological, psychological, and social factors interact to influence health.


Our team uses standardized assessments to understand the interpersonal and brain-behavior functioning of examinees presenting with pain, psychiatric, neurological, and related problems. 

Clinical and Forensic Psychology


Is there a clinical problem? Behavioral? Emotional? Substance use?

If so, does it impact the medico-legal situation?

"To a reasonable degree of medical and scientific certainty..." what are the examiner's opinions?

Consultation and Training

Whether it's helping out a risk/threat assessment team, reviewing records for attorneys, or "thinking aloud" about a particular medical or law enforcement problem, we enjoy bringing our unique training and years of experience to interdisciplinary consultations.


Having trained over 1,000 clinicians in forensic mental health issues, we enjoy teaching and training opportunities in graduate and medical school settings in the US and Caribbean.

Complex psychological evaluations happen not only in office settings,

but also in hospitals, jails, public safety agencies, and courtrooms

around the southeast.   ​

In addition, real-time telemedicine resources allow face-to-face evaluations and medico-legal consultation around the country.

Frequently Asked Questions

What is involved in a complex evaluation?


To address specific medico-legal referral questions from a variety of referral sources, our complex evaluations may include interviews and mental status examinations with an individual, collateral information from others about the individual, psychological and neuropsychological testing, review of relevant background records, and sometimes medical laboratory testing and focused medical examination.

Do you accept insurance?


​No.  Health insurance companies do not provide coverage for medico-legal evaluations. For the last eighteen years, we have chosen to avoid the problems associated with billing, panels, conflicts of interest, and "decision-making by clerks" that come with accepting health care insurance.  


Due to our level of training and experience in both psychology and medicine, we do not accept referrals for complex evaluations for reduced fees.  Also, we do not provide evaluation services under any “managed care” or “subcontractor” arrangements that require reduced fees.

I'm a student interested in a forensic psychology career.  What advice do you have?


​Be very clear that the work is not what is depicted on television and in the movies.  Please know that you must first be trained as a psychologist (Ph.D. or Psy.D.) to further specialize in forensic or other specialty areas in psychology.  There are only about 400 board-certified forensic psychologists and about 75 board-certified police psychologists in the nation. 


Students, do your homework and use the mainstream links on our "resources" page to learn about psychology as a profession and forensic and police psychology as areas for specialization.  Good luck, and follow your interests! Do be very suspicious about free-standing "forensic" and other psychology programs that don't qualify you for licensure in your state.  Also, be wary of the many websites that promote forensic and police psychology as "profiling" and criminal case investigation.  Also, be critical of sensational books written about these psychological specialties by non-psychologists. (Our request of you:  Please don't contact us for "interviews" for your classes.  We receive 5-10 calls or emails for such requests per month and cannot commit the time to respond.)

What advice do you have about careers in psychology and medicine?


​Based upon our experiences in psychology and medicine (PA-C), we believe there will be many opportunities 1) for psychologists with specialty training/experience, 2) psychologists with specialty training/experience in primary care settings (clinical health psychology), and 3) for PA-Cs and NP-Cs with training/experience in behavioral health challenges.


Forensic, and police, and public safety psychology are areas in the profession that are expanding.  Both combine clinical, counseling, assessment, and I-O psychology skills to support the legal system and the agencies and individuals who provide our safety and security.  (Contrary to the 24/7 media driving public perception, we continue to live in the safest era of homo sapien history!)


Finally, neuroscience and the gut microbiome - in our opinion - will continue to be rapidly expanding frontiers impacting clinical and research medicine and behavioral health over the next decade.  When asked about choosing a major, we suggest considering a double major in biology and psychology - then finding an area of interest/passion and going for it!
