About

I am a licensed psychologist in New York, currently working as a testing psychologist at LifeStance Health. As of October 2025, I completed my postdoctoral psychology fellowship at the Westchester Institute for Human Development. I graduated from a doctoral program at Pace University with my PsyD in school-clinical child psychology in 2024. I completed my predoctoral internship at JCCA, a residential treatment center where I worked with children and adolescents with educational, behavioral or emotional challenges. Prior to that, I have completed school psychology practica at The Birchwood School and Clarkstown High School South. I have seen child and adult clients as a psychologist-in-training at the McShane Center for Psychological Services, affiliated with Pace University.
