My ideal clients are motivated for change and seeking clarity around their mental health. They may be experiencing anxiety, depression, ADHD, sleep disturbances, or mood instability that is impacting daily functioning. Many feel misdiagnosed, overwhelmed, or stuck despite prior treatment. With nearly two decades of clinical experience, I provide structured, evidence-based psychiatric evaluation and medication management. Treatment is individualized, collaborative, and focused on measurable improvement. When clinically appropriate, medical cannabis may be considered in accordance with New York State regulations and guidelines.
I specialize in psychiatric evaluation and medication management for ADHD, anxiety, depression, and mood disorders. I provide clear diagnosis, structured treatment planning, and ongoing monitoring to ensure safety and effectiveness. My approach is individualized, evidence-based, goal-oriented, and focused on functional improvement.
If you are feeling overwhelmed, misunderstood, or frustrated with prior treatment, you’re not alone. Seeking help is a meaningful step. I provide a direct, supportive approach focused on clarity and real progress. When you’re ready for a more structured and effective path forward, I’m here to help.
