I’m Dr. John Crimmins. With over 25 years of clinical experience specializing in Addiction, Eating Disorders, and Workplace Trauma, I founded this institute to make evidence-based psychological training accessible worldwide.
Unlike larger impersonal platforms, I believe in a mentored approach to learning. I personally tutor every participant on our courses, providing direct feedback and professional guidance as you progress. This ensures you aren’t just reading theory—you are gaining clinical insights from a PhD-level practitioner dedicated to your success.”
