Feeling overwhelmed, anxious, or depressed? Struggling with trauma, discrimination, gender-based violence, sexual assault, or the stresses of immigration and resettlement? You want a safe, validating space where your experiences are understood and honored. You’re seeking guidance to process pain, reclaim control, build resilience, and reconnect with joy, confidence, and meaningful connection. This is a space for those ready to heal, embrace their strengths, and transform challenges into growth and self-discovery.
Through trauma-informed psychodynamic therapy, we explore your experiences from an intersectional perspective, process difficult emotions, and rebuild inner strength. Support is provided for stress, anxiety, depression, racial trauma, gender-based harm, and life transitions—helping you reclaim control, joy, and meaning.
Healing from trauma, discrimination, or life challenges can feel isolating. In a safe, collaborative, and culturally aware space, you’ll uncover strengths, process pain, and reconnect with joy, purpose, and community. I am here to support you when you're ready to take the next steps toward greater wellness and self-discovery.
