I'm a licensed clinical psychologist based in New York City. I completed my doctoral training at Nova Southeastern University — an APA-accredited program — and my predoctoral internship at Nassau University Medical Center on Long Island, where I worked across community mental health and hospital settings.

My clinical work is grounded in ACT, CBT, Cognitive Processing Therapy, and Prolonged Exposure. I also work with couples using the Gottman Method (Level 2 trained), because relationships are often where our psychological struggles show up most clearly. I offer sessions in both English and Spanish.

Outside the therapy room, I've contributed to research on personality and emotional functioning in Mixed Martial Artists — work that deepened my thinking about performance, stress tolerance, and what it takes to compete under pressure. That perspective shapes how I work with high-performing clients today.

At the core of everything I do is a simple belief: people can change, and the right relationship makes that change possible.
