Professional Bio

Life doesn’t stop with a diagnosis - it shifts. I'm here to help adolescents and adults navigate the landscape of chronic health conditions, neurodivergence, and mental health diagnoses using ACT therapy, a powerful approach that fosters acceptance and connects you with what truly matters. Whether someone is adjusting to a new diagnosis, facing ongoing stressors, or simply feeling overwhelmed, I offer neuroaffirming care that honors each person's unique story and supports their journey toward a meaningful life.

I am a licensed psychologist and nationally certified school psychologist based in Pennsylvania, providing individual therapy, executive skills support, and assessment in person (Bryn Mawr, PA) and through telehealth in 43 states. I work with teens and adults navigating anxiety, depression, ADHD, autism, learning differences, and chronic health conditions.

If you're feeling stuck, overwhelmed, or just trying to figure out the next right step, you're not alone. I’d love to connect and learn more about what’s going on for you. Therapy doesn’t have to be intimidating. It can be a space to get curious, build clarity, and move forward in ways that feel doable and aligned with your values.
