Many of the adults I work with are navigating anxiety, burnout, overwhelm, or the feeling that they've spent years adapting and still don't feel like themselves. I specialize in ADHD and neurodivergence, and it’s work I care about deeply.
I believe real change happens when insight is paired with action.
I have over 3 decades of experience working in the fields of mental health and social work. I work with youth, adults, and couples who are struggling with trauma, depression, anxiety, ADHD, autism, relationship issues, and school refusal.
I have spent my career learning and translating theories into practice with individuals, families, couples, and groups. For the last few years, I've gained deeper knowledge working with trauma, anxiety, couples, and the LGBTQIA+ population.
