I am a Certified EMDR Therapist with advanced training in Internal Family Systems (IFS), specializing in PTSD, trauma, mood disorders, anxiety and other challenges. My approach is relational and humanistic, offering a warm, compassionate, and safe space where your story is honored without judgment. As an LGBTQIA+ ally, I affirm all identities and acknowledge the impact of systemic injustices, helping clients move toward healing, clarity, and deeper self-connection

I help clients heal from painful experiences, reduce anxiety, and feel more grounded. I offer a non-pathological approach that honors your nervous system and the ways it has protected you. Through EMDR, IFS, and other evidence-based methods, I provide a safe space to build resilience and lasting change.

Healing can feel daunting, but you don’t have to do it alone. In our work together, you remain in control of your healing journey. I offer a safe, compassionate space where your pace and goals guide each step. When you’re ready, it would be an honor to walk beside you toward healing and growth.
