Senior Faculty

Dr. Karen Kranz, R. Psych.

Dr. Karen Kranz, R. Psych., is first generation Canadian has been a psychologist in private practice in Vancouver, Canada since 2000. Her areas of interest in AEDP are making the work with clients and therapists increasingly more relational and experiential. She is continually challenged and intrigued by core and pathogenic emotions.  

After the Immersion course, she began supervision with Dr. Fosha. “At that time, all that interested me was becoming a better clinician, AEDP certification as a therapist and supervisor and becoming faculty were never my ambitions. However, as I deepened into both my knowledge and experience of AEDP and in the AEDP community, I realized that it was through the process of certification as a therapist, as a supervisor, and now with teaching and writing that I was becoming a better therapist.”

With AEDP, Dr. Kranz says she “found a therapeutic home and a community of colleagues when I did not even know I was looking for one, or perhaps more aptly wasn’t looking for one because I did not believe such a home existed.”

Nationally and internationally, Dr. Kranz supervises and has taught Immersion Courses, Essentials Skills (ES1), Advanced Skills (ES2), and Core Training. Dr. Kranz has a chapter titled “The first session in AEDP: Harnessing transformance and cocreating a secure attachment.” In Diana Fosha’s (2021)  book “Undoing Aloneness and the Transformation of Suffering into Flourishing: AEDP 2.0.” She has also written a paper titled “Making AEDP supervision relational and experiential: Cultivating receptive affective capacity in supervisee and client” which is published in the AEDP Journal Transformance.”
