Are you feeling a pull toward more clarity, more connection, more ease in how you move through your relationships and your life? Therapy can be a space to turn toward that pull with intention.
Whether you’re exploring relational patterns, preparing for partnership, moving through a life transition, or making sense of loss, our work together invites a deeper understanding of yourself and the ways you connect with others. For couples, this is a place to strengthen communication, deepen intimacy, and build a shared foundation with care and awareness. Together we can slow things down and listen more closely to what’s unfolding.
With over a decade of experience as a registered social worker, I work with individuals and couples using a psychodynamic, somatic, attachment-based, and trauma-informed approach. My focus is on supporting meaningful, lasting change and helping you cultivate relationships that feel grounded, connected, and fulfilling.
My style is warm, grounded, and direct. I value creating a space where you feel safe and supported, while also inviting thoughtful reflection and gentle challenge around the patterns and beliefs shaping your experience. If this speaks to you, I invite you to reach out and explore whether we’re a good fit.
