Core Training – Multi-Faculty – Vancouver 2020

Please read about AEDP Core Training, including our prerequisites, here

A note from AEDP Sr. Faculty member Dale Trimble,  describing Core Training in general as well as his approach to organizing and leading this Multi-Faculty Core Training:

I’m excited to announce Core Training 2020 in beautiful Vancouver, BC. My own core training was 10 years ago. I found the experience to be one of the most personally and professionally rewarding experiences of my 40 plus years of being a therapist. My vision is to make this core training just as effective for you. Together we will create safety and support so that we witness each other’s work with curiosity and delight. You will have the wisdom and experience of three or maybe even four different faculty, over the course of our five weekends. By witnessing different ways of melting defense, processing emotion to completion and holding the magic of core state; you will come to find your own unique style of being your therapist at best.

If you are attending from outside of Canada you can take advantage of our lower dollar (~25% less as I write this). Our location is central to Vancouver and convenient to rapid transit from the airport, reasonably priced and comfortable hotels or Air B&B’s. Feel free to contact me directly at if you have questions.     

This multi-faculty Core Training will meet for 5 weekends over the course of six months. The group will be limited to 10 participants to create group safety. Each weekend includes didactic and video presentation by the weekend’s leading faculty member, followed by one hour for each group member to show tape of their own work and receive both faculty supervision and supportive feedback from group members. Core Training is one of AEDP’s most powerful learning experiences for integrating AEDP theory into your own clinical acumen.

Prerequisites for joining the Core Training group: a) completion of Immersion and/or Essential Skills 1 and b) you must be videotaping your client sessions as bringing your own video is an essential part of the training. If you have not taped your sessions before, feel free to email me for guidance, 

Some core training groups are made up of individuals who are relatively inexperienced in AEDP; others are made up of relatively advanced AEDPers. Applications are required for the Training and every effort will be made to put together a cohesive group.

Core Training Weekend Dates & Faculty will be as follows:

January 18-19, 2020: Miriam Marsolais

Feb 29-March 1, 2020: Dale Trimble

April 4-5, 2020: Dale Trimble

Meet the Faculty for this Core training:

Dale Trimble, MA

In 1981 Dale co-founded the first court ordered treatment program for men who assault their partners in the province of British Columbia. He was the lead author of the Canadian syllabus for CP 602 – The Psychology of Trauma and Interpersonal Violence for City University of Seattle, Vancouver, BC campus, where Dale has taught and supervised graduate students. Known as a Canadian expert on working with men, Dale has travelled throughout Canada providing training for therapists on compassionate ways of helping men change.

Dale has a private practice in Vancouver, BC where he works with individuals and couples focusing on resolution of early childhood trauma, anxiety, interpersonal violence and depression. His background includes extensive training in Emotionally Focused Couples therapy, EMDR and the clinical application of meditation and mindfulness practices to healing. When Dale first connected with AEDP in 2009 he knew that he had found his therapeutic home. Since then he has trained extensively in AEDP with Diana Fosha and Ben Lipton.


Miriam Marsolais, PhD

Miriam Marsolais, PhD, is a licensed psychologist and Jungian Analyst in Berkeley, California.  She served as AEDP Faculty from 2014 until  2018, when she transitioned to her current role as AEDP Faculty Emerita & Supervisor. In addition to her private clinical practice, Dr. Marsolais provides supervision to therapists wishing to train in AEDP and the certified AEDP therapists on the Supervisor Certification track.  She also hosts and leads retreat-style AEDP group supervision weekends in the beautiful natural setting of The Sea Ranch on the northern California coast.

As a young adult Dr. Marsolais performed as a violinist, was a nun and taught high school science and mathematics. Following a near-fatal burn injury, her life took a major turn and her passions were redirected towards the study of history, psychology and Eastern mind/body practices.  Dr. Marsolais is inspired and challenged by AEDP’s dynamic, integrative clinical approach and is grateful to have found her professional home in the AEDP community. She is deeply engaged in extending AEDP practice into the domain of the sleeping self through relational andphenomenological work with dream experience.  Through this work, she is exploring new pathways to healing from early relational trauma and PTSD. She is also exploring the resonances between AEDP and East-West mind/body practices, and how integration of these traditions with AEDP can enrich AEDP practice, training and supervision.
