Jessica Koury
Life can feel overwhelming when you're carrying the effects of trauma, stress, fear, or experiences that others may not see. I offer a compassionate, supportive space where children, teens, and adults can feel understood, safe, and empowered to heal.
As a Certified Clinical Trauma Professional, I work with individuals experiencing complex trauma, dissociation, suicidal thoughts, violence-related experiences, anxiety, and sports performance concerns. I also understand the impact that stigma, marginalization, and systemic barriers can have on mental health and wellbeing.
My approach is individualized and integrates somatic therapy, EMDR, mindfulness, and parts work. Together, we explore how past experiences and current challenges may be shaping your life while building resilience, confidence, and a stronger sense of connection to yourself and others.
Healing is not about forgetting what happened—it is about creating new possibilities for moving forward. Whether you're feeling stuck, overwhelmed, or ready for change, I am here to support your growth and help you reconnect with your strengths.
