Daniel Polonsky Psy.D. – Postdoctoral Fellow

I completed my Doctor of Psychology degree at Adler University with an emphasis in Clinical Neuropsychology. My predoctoral internship was at Immaculata University Psychology Internship Consortium (IU-PIC) where I conducted therapy and neuropsychological evaluations at Rutgers University - Camden. 

Regarding neuropsychology, I specialize in working with children, however, my training encompasses the lifespan. I work with diverse populations with a range of complex neurological conditions (e.g., epilepsy, cerebral palsy, and hydrocephalus etc.) as well as dementia, sleep disorders, and neurodevelopmental and affective conditions. Regarding psychotherapy, my training and current approach utilizes a combination of cognitive behavioral and existential therapies to allow my patients to achieve a fulfilling life, develop meaningful connections, and overcome complex obstacles. 

At present, I am a post-doctorate fellow in clinical neuropsychology at ARCC Neuropsychology. I conduct intake evaluations, neuropsychological and psychological assessments, and provide feedback to patients across the lifespan who have a wide array of affective and neurodevelopmental disorders as well as degenerative diseases and complex neurological conditions. I work in diverse settings (e.g., outpatient clinic, neurorehabilitation and psychiatric units of hospitals, and nursing homes) in both English and Russian (when appropriate). Additionally, I work closely with our staff and training students. I lead didactics, as well as group and individual supervision. 

Outside of the professional environment, I am avid golfer, musician, and reader. Additionally, I enjoy traveling, attending plays and orchestra concerts, and exploring new cultures.”
