Profile Headshot


Dr. Krellman is an Associate Professor of Neuropsychology and a provider on the Neuropsychology Service. He is board certified in both clinical neuropsychology (ABPP-CN) and rehabilitation psychology (ABPP-RP) by the American Board of Professional Psychology. He is one of only approximately 20 clinicians in the US and Canada certified in both specialties, which attests to his specialization in both the assessment and treatment of cognitive, emotional, and behavioral symptoms due to neurological injury or disease. He has extensive experience in the neuropsychological evaluation of individuals with mild cognitive impairment or dementia due to neurodegenerative diseases, brain tumors, and traumatic brain injury as well as expertise in concussion evaluation and symptom management.

Dr. Krellman earned his doctorate in clinical neuropsychology from the City University of New York, where his dissertation work focused on neuroanatomical and behavioral phenotyping of inbred mouse strains to develop animal models of neurodevelopmental disorders. He completed his predoctoral internship training in clinical neuropsychology and geriatric psychology at North Shore University Hospital and Long Island Jewish Medical Center (now Northwell Health System), and he completed his postdoctoral fellowship training in clinical neuropsychology and traumatic brain injury rehabilitation research at the Icahn School of Medicine at Mount Sinai.

In addition to his clinical duties on the Service, Dr. Krellman is a co-investigator or consultant on research studies examining neuropsychological outcomes in both neurological and non-neurological patient populations. His previous research focused on developing rehabilitation treatments and assessing cognitive and psychiatric outcomes in survivors of moderate to severe traumatic brain injury. 

He is the President of the New York Neuropsychology Group (NYNG) and Co-Chair of its Training and Mentorship Committee. Relatedly, he co-directs training programs for predoctoral externs and postdoctoral fellows on the Service with his colleagues.

Dr. Krellman's doctoral research focused on cognitive, behavioral, and neuroanatomical phenotyping of inbred mouse strains. His clinically-focused research began with postdoctoral training in traumatic brain injury (TBI) rehabilitation research at the Mount Sinai School of Medicine, where his fellowship work focused on identifying participant characteristics associated with loss-to-followup in longitudinal outcome studies of individuals with moderate to severe TBI and the development of group interventions to treat executive dysfunction following TBI. His latest research has focused on the development of interventions to treat long-term sequelae of moderate to severe TBI, such as emotional dysregulation and fatigue, as well as the incidence and predictors of neurological and psychiatric disorders following moderate to severe TBI. He has authored book chapters and peer-reviewed articles in the area of TBI rehabilitation.
