Hello! I’m Lex, a board-certified psychiatric nurse practitioner with 4 years of nursing experience. I provide care to clients across New York, specializing in anxiety, depression, insomnia & sleep issues, bipolar, life transitions, obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD) / trauma. My doctor in nursing specializing in psychiatry was completed at Columbia University where I developed a strong foundation in evidence-based mental health care.
As a psych NP, I treat a broad spectrum of mental health conditions in addition to my specializations.
I believe that meaningful and sustained change comes from a deepened understanding of oneself. I provide a warm and consistent space to support patients in developing their own gentle curiosity about themselves, their experiences, and the problems which bring them into treatment. I utilize a psychodynamic approach, which means I am attuned to unconscious processes and appreciate the ways in which observable symptoms may communicate inner conflicts, anxieties, and wishes. Listening in for these parts of the self allows for greater self-awareness, flexibility, and fulfillment. I view medication as a tool to provide stability and symptom relief in order to improve daily living and facilitate the therapeutic process, and I work collaboratively with patients to determine when it is necessary as well as when it is no longer needed. I understand the complex experience of taking psychiatric medication and bring sensitivity and careful attention to this component of treatment. In addition to medication, I work with patients to build and strengthen their coping skills.
