I'm a licensed clinical psychologist serving New York City and clients across New York via telehealth. 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; Spanish is actually my first language, and you can read more about therapy in Spanish here. Values work sits at the center of how I practice; you can try a small piece of it yourself with my free ACT Values Assessment.
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.

Frequently Asked Questions
Answers to what people usually ask before reaching out.
Do you accept insurance?
Yes. I'm in-network with Aetna, and I have a direct intake path for Northwell Health employees. Both book through the Sessions Health portal. For out-of-network plans, I can provide a superbill for reimbursement.
Do you offer online therapy?
Yes, all sessions are available via telehealth. I'm PSYPACT-authorized to see clients across 40+ participating states, not just New York.
Do you offer therapy in Spanish?
Yes. Spanish is actually my first language: I'm a Spanish citizen and grew up with a Spanish mother. I offer sessions entirely in Spanish, entirely in English, or a mix of both.
What is ACT therapy?
Acceptance and Commitment Therapy (ACT) is an evidence-based approach that helps you relate differently to difficult thoughts and feelings, not by eliminating them, but by reducing their grip on your behavior. It's particularly effective for anxiety, OCD, depression, and burnout.
Do you work with couples?
Yes. I'm trained in the Gottman Method (Level 2) and work with couples navigating communication breakdowns, conflict, and relationship transitions.
What does a first session look like?
We start with a free 15-minute intro call. If it's a good fit, the first full session is a thorough intake. We cover your history, your goals, and what's bringing you in. From there, we build a clear treatment plan together.
How long does therapy take?
It depends on what you're working through and what you're hoping to get out of therapy. Some people make meaningful progress in a relatively focused period; others do better with longer-term work. There's no standard timeline. We'll talk about what makes sense for you from the start.
What are your fees?
My standard private-pay session fee is $250. Insurance-based rates vary by plan and payment path. For out-of-network plans, I provide a superbill you can submit for reimbursement, and you can estimate your out-of-pocket cost with the out-of-network calculator on this site. Email info@ovhpsychology.com with any questions.
Are you currently accepting new clients?
Yes, I'm currently accepting new clients. You can book directly through the Sessions Health portal, or reach out by email first.
What's the difference between a psychologist and a therapist?
A psychologist holds a doctoral degree (PsyD or PhD) and has completed additional years of supervised clinical training and a formal internship. In New York, psychologists are licensed to provide diagnosis, assessment, and treatment. The title 'therapist' is broader and includes licensed social workers, counselors, and marriage and family therapists.
