Healing from complex trauma, sex addiction, or betrayal isn't just about managing symptoms, it's about becoming whole. At The Niagara Centre for Healing & Recovery, we believe that lasting transformation happens when every part of you is seen, understood, and welcomed. I'm Katherine Castello, a Certified IFS Therapist (Level 3) and Certified Sex Addiction/Partner Trauma Therapist. My practice is built on one core conviction: shame heals in the presence of safety. Whether you're carrying the weight of a complicated past or rebuilding trust after betrayal, I'll walk alongside you, You don't have to do this alone.
At the Niagara Centre for Healing & Recovery, we believe real healing begins when you feel truly safe. Using evidence-based approaches — IFS, EMDR, EFT, Deep Brain Reorienting, and Intimacy From the Inside Out — we work with individuals, couples, and families to move beyond survival and into lasting transformation.
Healing isn't linear, and it doesn't look the same for everyone. Whatever brought you here — complex trauma, sexual recovery, betrayal, or a quiet need for change — we offer a space to explore without judgment, supported by specialized assessment and personalized treatment planning. Contact the clinic today to take the first step in your healing journey.
