Background

I received my doctoral degree in clinical psychology in the PGSP-Stanford PsyD Consortium in Palo Alto, California. I completed my APA-accredited pre-doctoral internship at Rutgers University Behavioral Health Care in the child track and my APA-accredited clinical child postdoctoral fellowship at Northwell Health’s Long Island Jewish Medical Center, Zucker Hillside Hospital, with an emphasis in pediatrics. During my postdoctoral fellowship, I trained in Zucker Hillside’s Child Outpatient Department, Northwell Health Physician Partners LGBTQ Transgender Program, and Cohen Children’s Medical Center’s Hematology, Oncology, and Stem Cell Transplant division. In the Northwell Health Physician Partners LGBTQ Transgender Program, I was privileged to receive specialized training in the LGBTQIA+ community in a primary care setting.

I have also been trained in evidenced-based treatments for OCD, anxiety, depression, trauma, and emotion dysregulation as well as other more general childhood behavioral challenges in a variety of settings including Kaiser Permanente Medical Center, Rogers Behavioral Health, Stanford University School of Medicine/Lucile Packard Children’s Hospital, Stanford University School of Medicine Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) Clinic, and the Intensive Program for OCD at Bradley Hospital.
