As a Board-Certified Psychiatric Mental Health Nurse Practitioner, I partner with children, teens, and families to provide comprehensive, compassionate mental health care. My practice specializes in the evaluation, diagnosis, and treatment of ADHD, anxiety, Oppositional Defiant Disorder (ODD), depression, and OCD. I believe in looking at the whole child, blending evidence-based medical management with therapeutic support to help your child thrive at home, in school, and in life.

What uniquely informs my psychiatric practice is my foundational background in pediatric neurology. This specialized experience allows me to deeply understand the complex intersection between brain development, neurological functioning, and behavioral health. When treating conditions like ADHD or OCD, I look beyond surface-level symptoms to understand the underlying neurological drivers, allowing me to create highly precise, targeted treatment plans that standard approaches might miss.

I’m a board-certified Nurse Practitioner with over a decade of experience working in ICU. My background in ICU shaped how I understand the deep connection between physical and mental health, especially how stress, trauma, and anxiety often show up in the body. I transitioned into psychiatry after witnessing firsthand the emotional toll the pandemic had on patients, families, and healthcare workers. It became clear to me that supporting people’s mental health is just as essential as treating physical conditions.

**Important for New Jersey patients seeking STIMULANT treatment:

Due to New Jersey state regulations, patients prescribed stimulant medications are required to attend an in-person visit at least once every three months. These visits are scheduled at my SoHo office in Manhattan.

Please note that there is a $100 facility fee for in-person visits to cover the cost of the clinical space. This fee is separate from insurance and is due at the time of the visit.**

As your mental health provider here's what I want you to know about me:

• I listen first
• I believe in collaboration
• I treat the whole person
• Medication is a tool, not a requirement.
• There is no shame in seeking help.
• Progress is possible.

Your mind and body are speaking—are you listening? As a board-certified Psychiatric Mental Health Nurse Practitioner with over a decade of experience in high-stakes intensive care, I understand what many overlook: mental and physical health are inseparable.

In critical care, I saw how stress, trauma, and anxiety manifest in the body—tight chests, sleepless nights, unexplained pain. And when the pandemic hit, I witnessed the silent emotional suffering of patients, families, and healthcare workers alike. That moment changed everything.

I chose psychiatry because healing your mind is just as vital as healing your body. If you’re feeling overwhelmed, exhausted, or like no one sees what you’re carrying—you don’t have to hold it alone. I’m here to help you reconnect, restore, and rise.
