I am a Harvard-trained clinical psychologist offering expert treatment for OCD and anxiety. My practice focuses on high-performing individuals who are accustomed to operating at high levels but find themselves caught in cycles of doubt, perfectionism, avoidance, and mental or emotional exhaustion. Many of my clients present as outwardly high-functioning while quietly feeling disconnected from their values and truest selves, often with the unsettling sense that life is passing by. My aim is to help you create the breathing room to pursue an ambitious life without sacrificing sustainability or wellbeing.
I have trained and conducted research at leading academic institutions across the US and UK and approach my clinical work with the highest level of integrity and expertise. I specialize in gold-standard, evidence-based treatments like Exposure and Response Prevention (ERP), Acceptance and Commitment Therapy (ACT), and Cognitive Behavioral Therapy (CBT).
Therapy with me is a compassionate, collaborative, and tailored experience — not a one-size-fits-all formula. I honor the complexity of your experiences, including how culture, identity, and environment shape who you are. While I lead with warmth and compassion, I’m also here to gently challenge and support you in creating meaningful change.
