Trauma-informed and compassionate IFS training that brings theory to life.

Hi, I'm Marie Tierney, an IFS Certified Therapist, Approved Clinical Consultant, and Trainer for the Internal Family Systems Institute.

I bring the heart of a healer to the art of teaching. My work is rooted in many years of clinical experience working with adults impacted by childhood trauma, addiction, and complex challenges. I don’t just teach IFS theory – I bring it to life.

As Ireland’s first IFS trainer and founder of IFS Ireland, I actively support the growth of the IFS community in Ireland. My workshops and trainings are known for their warmth and accessibility. I translate IFS wisdom into practical skills therapists can use immediately.

I have been told that my passion is contagious. Through supervision and consultation, I mentor therapists with genuine care. I offer expert guidance grounded in clinical wisdom for those seeking to specialise in trauma-informed IFS practice.
