For more than twenty years, I have had the privilege of walking alongside adolescents, adults, and couples during some of the most difficult and meaningful seasons of their lives. I believe that sometimes it can be difficult to see beyond the darkness in front of us. My role is to listen without judgement while helping you find your way toward the light again.

I am passionate about helping clients cultivate greater balance, vitality, and overall well-being in their lives. I have experience working with individuals facing a wide range of mental health concerns, including depression, anxiety, trauma, bipolar disorder, OCD, ADHD, disordered eating, substance use disorders, and insomnia. I earned my degree from Hunter College in New York City, where I developed a strong foundation in evidence-based, client-centered care.

I work with adults navigating anxiety, career and life transitions, grief, and questions of identity and purpose — whether that's a 20-something rethinking their path, someone reassessing a career after years in it, or an older adult navigating retirement, caregiving, or the shifts that come with later life. My approach is collaborative and grounded: you'll leave sessions with more clarity than you came in with, not just more to think about.

I came to this work after a first career in banking. I understand the pressure, identity, and burnout that come with corporate life firsthand — and what it takes to actually rebuild around what matters to you, whatever stage of life or career you're in. I hold a Master's in Mental Health Counseling from Yeshiva University.

Great to meet you! I am a DNP-prepared, dual-certified Psychiatric and Acute Care Nurse Practitioner with over 15 years in healthcare. I specialize in helping adults and adolescents navigate complex mental health journeys, from daily management to high-acuity needs. My approach is rooted in holistic, evidence-based care, tailored specifically to you. I take the time to listen, working collaboratively to create a stable, supportive environment where you feel empowered. Whether we are focusing on medication management or therapeutic support, my goal is to help you feel grounded, heard, and in control of your well-being.

I understand that the decision to seek help for mental health needs can be a nerve-racking and scary process. When it comes to patient care, I am most passionate about the preservation of dignity and making my patients feel seen. I meet fear or nervousness with acceptance, encouragement, and knowledge.
