Many people come to me because their emotions feel too intense, too unpredictable, or too hard to manage. You might notice worry thoughts, mood shifts, or urges that pull you away from your goals, relationships, or sense of self. Strong emotions can be overwhelming — but they’re also deeply human. Emotion regulation isn’t about getting rid of feelings; it’s about learning to ride the wave without letting it carry you off course.
I am a DBT‑Linehan Board of Certification, Certified Clinician — the gold standard for DBT providers. I offer adherent DBT individual therapy and DBT skills training in both group and 1:1 formats. My approach integrates evidence-based treatments including cognitive behavior therapy (CBT), exposure therapy, and trauma-informed care.
Starting therapy — whether for yourself or your child— can feel overwhelming or confusing. Reaching out is a meaningful first step. I offer a free 15-minute consultation to discuss your goals, clarify next steps, and explore whether we may be a good fit to work together.
