Our staff include licensed, doctoral-level psychologists with expertise in the assessment of a variety of conditions including but not limited to: Traumatic brain injury, dementia, ADHD and learning disorders, as well as pre-surgical and pre-employment psychological evaluation and screening.

Our clinicians are trained in multiple psychotherapeutic approaches. We employ evidence-based approaches such as cognitive behavioral therapy (CBT) and mindfulness-based cognitive therapy (MBCT) to treat patients with primary and secondary psychological disorders. We also offer cognitive therapy to patients with mild brain dysfunction to help them learn how to compensate and to promote their highest level of independence and daily functioning. At DPR, we strive to provide comprehensive, accurate, and reliable evaluations coupled with supportive and empathic treatment.
