How I Can Help

Evaluations & Therapy, Tailored To You

Every person who reaches out is at a different point, and my services are built to meet you there. I am an expert in the very early diagnosis of Autism Spectrum Disorders (ASD) in children as young as 8 months of age and up to 5 years of age. For adults, I offer individual psychotherapy grounded in proven methods. All care is available in English and Spanish, in person in New York City or by telehealth.

Your First Step, Made Simple

Getting started is simple. Reach out through the contact form or by phone, and we will talk about what you are looking for and whether we are a good fit. From there, I schedule your evaluation or first psychotherapy session, in person or by telehealth. For evaluations, you receive clear findings you can act on; for psychotherapy, we begin at a pace that feels right for you.

Reframing Thoughts

Using Cognitive Behavioral Psychotherapy (CBT) and Rational Emotive Behavior Psychotherapy (REBT) to shift the thought patterns and beliefs that hold you back.

Finding Acceptance

Drawing on Acceptance and Commitment Psychotherapy (ACT) and Mindfulness-Based Cognitive Psychotherapy (MBCT) to help you live in line with your values.

Steadying Emotions

Applying Dialectical Behavior Psychotherapy (DBT) and trauma-informed care to help you regulate emotions and heal from difficult experiences.

Who You'll Be Working With

I am a licensed clinical psychologist with over 25 years of experience, and I trained in Rational Emotive Behavior Psychotherapy directly under its founder, Dr. Albert Ellis. My work is grounded in proven methods and delivered with genuine warmth, in a space where you feel understood and never judged. I would be glad to tell you more about my background and approach.

I am a Clinical Psychologist with over 25 years experience conducting Cognitive Behavioral Psychotherapy (CBT) with adults. Aside from my extensive educational and clinical experience, my work is influenced by my lived experience, as an immigrant, fully fluent in Spanish, first generation college student, and parent to neurodivergent youth. I offer a professional and direct, yet warm and personable style to effectively help my adult clients address the stressors and mental health challenges they are facing, including relationship issues, adjustment disorders, depression, and anxiety. I am also an expert in the early diagnosis of Autism Spectrum Disorders, conducting Early Intervention evaluations of children as young as 8 months of age and up to 3-5 years of age, and have worked with parents and siblings of individuals presenting with ASD, ADHD, and other conditions.
