Introduction: The Expanding Landscape of Trauma-Informed Therapy

I’m continually inspired by how our field is rapidly evolving, with new trauma-informed therapy methods empowering clinicians and clients alike. In 2025, therapists have more evidence-based options than ever for addressing the nuanced needs of trauma survivors. In this guide, we’ll map the full range of trauma-informed therapies, answer advanced FAQs, and compare the newest online and in-person training opportunities—including Linda Thai’s acclaimed nervous system regulation therapy approach and techniques.
