Many people come to therapy feeling numb, disconnected, or stuck—functioning on the outside while something essential feels missing inside. I work with adults, particularly men, whose struggles often trace back to early attachment wounds and complex trauma. My approach is relational and trauma-informed, focused on understanding how old patterns replay in the present and within the therapy relationship itself. Through careful, respectful exploration, therapy becomes a place to reconnect with yourself and experience real, lasting change.
My approach is integrative—rooted in non-directive, person-centered psychotherapy and informed by relational, attachment, and contemporary trauma theory. Together, we explore what’s happening beneath the surface, allowing therapy to be tailored to your unique needs through deep exploration while staying grounded in the present.
Together, we’ll explore the impact of past wounds, attend closely to what unfolds between us in session, and create new experiences of connection and meaning. My goal is for you to leave therapy not just with insight, but with a felt sense of possibility in how you relate to yourself and others.

I help men and couples struggling with disconnection, conflict, and the weight of past wounds. In our work, we'll identify patterns that keep you stuck and explore new ways of relating in the present.
