About Dr. Jaime Marrus

Jaime Marrus is a NYS Licensed Psychologist who earned her Ph.D. in Clinical Psychology, with a specialization in childhood/adolescence, from St. John’s University.  She graduated summa cum laude from New York University where she received her Bachelor of Arts in Psychology, with minors in Child & Adolescent Mental Health Studies, American Sign Language, and Business.  In addition to her work in this practice, she currently serves as a consulting psychologist, at a private Waldorf school in Manhattan. Previously, she provided play therapy and conducted evaluations for preschool-aged children presenting with a range of developmental delays, as well as consultation for multidisciplinary teams in a therapeutic preschool.

Dr. Marrus’s passion for and expertise in the diagnostic assessment and treatment of neurodevelopmental disorders of relating and communicating, including autism spectrum disorders (ASD), developed as a result of a variety of clinical experiences.  Such experiences include working as a clinician on inpatient and outpatient units at Nassau University Medical Center (NUMC), in the Psychology Department of the Milton Hershey School in Hershey, Pennsylvania, and most especially, at the Rebecca School, a DIR/Floortime school for children with ASD and related disorders ranging from 4 to 21 years of age, where she was first introduced to the DIR/Floortime model.  

Additionally, Dr. Marrus completed a post-doctoral fellowship with a specialization in clinical child psychology and developmental disabilities at the Westchester Institute for Human Development (WIHD). At WIHD, she conducted psychological evaluations for young children in or applying to Early Intervention and the Committee on Preschool Education in order to clarify diagnoses, evaluate strengths and areas of need, and provide recommendations, as well as participated in research projects related to the early diagnosis of autism spectrum disorder. She also provided consultation and therapeutic services during a rotation at the United Cerebral Palsy therapeutic preschool in White Plains, NY.  Lastly, she completed the Leadership and Education in Neurodevelopmental Disabilities (LEND) fellowship program, which is an interdisciplinary leadership training program, funded by the Maternal and Child Health Bureau of the federal government. The program focuses on the core values of cultural competence, family-centered practice, life course perspective, interdisciplinary approach, and evidence-based practice, and enhanced Dr. Marrus’s already strong commitment to working with children and families from a systemic, multidisciplinary, strengths-based approach to provide the best and most comprehensive support for diverse clients and their families.

Dr. Marrus has received training in the DIR/Floortime model, cognitive behavioral therapy techniques, and advanced training in the Collaborative and Proactive Solutions model by Dr. Ross Greene. Her work is most heavily influenced by the theories and techniques of Dr. Greene, Dr. Stanley Greenspan, Dr. Stephen Porges, Dr. Stuart Shanker, and Dr. Mona Delahooke. Dr. Marrus is a member of the American Psychological Association (APA), and of APA’s Division 53 (Society of Clinical Child and Adolescent Psychology).
