How It Works

Determine Fit

Determine if our services are a right fit for you.

Evaluation Appointment

Psychological testing can take anywhere from four to ten hours and can be split over several days.

Report Creation

From the time testing is complete, it will take two weeks on average to review your results and create a report.


Once your testing report has been completed, we schedule a one-time meeting to review the findings of your assessment. We discuss your results in detail, answer any questions you may have, and provide relevant referrals, as needed.
