I’m a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) dedicated to providing compassionate, evidence-based mental health care for individuals navigating life’s challenges. My clinical background spans addiction recovery, mood and anxiety disorders, trauma, ADHD, and women’s mental health.

I started specializing in CBT for children in 1998 — and the 28 years since have taken me through residential programs, day treatment, outpatient clinics, and public schools. That breadth of experience means I've worked with people across the full range of what life can throw at someone, and I've learned what actually helps.

In 2021, I completed a Certificate of Advanced Graduate Studies in Resiliency in the Helping Professions — deepening my focus on the skills that make change stick: emotional regulation, realistic optimism, and self-compassion. These aren't just techniques. They're the foundation of what I help clients build.

I work with children (ages 6+), adolescents, and adults on anxiety, depression, trauma, ADD/ADHD, family stress, and anger. I'm based in Central Massachusetts and offer telehealth across the state.
