Jaqueline Maria Cassar

Jaqueline was first introduced to AEDP during her psychology studies at PUC-Rio. Her connection with the model deepened through a two-year training program with Regina Pontes and Maria Cândida, pioneers in introducing AEDP to Brazil. In 2012, she traveled to Boston to attend the AEDP Immersion Course, where she met Dr. Kari Gleiser, who would later become her supervisor. Kari’s loving and attuned
presence had a profound impact on Jaqueline’s development as a therapist, inspiring her to embody the healing essence of AEDP in both clinical and supervisory settings. She went on to complete the Essential Skills and Advanced Skills trainings in New York, and has been assisting in AEDP trainings for many years, supporting the growth of new therapists with presence, clarity, and deep respect for the process.

Jaqueline is also trained in Somatic Experiencing, where she continues to assist in trainings, and is a certified Mindfulness Instructor through Mindfulness Training International, integrating breathwork and contemplative practices into her work.
In addition, she holds formal training in both Reichian Analysis and Cognitive Behavioral Therapy (CBT), bringing a rich integrative perspective to her clinical and supervisory relationships. Her approach to supervision is experiential, warm, and supportive — honoring the wisdom of the body, the power of presence, and the deep healing that emerges from relational safety and emotional truth.

Hoai-Thu Truong, PhD

Hoai-Thu Truong a Certified AEDP Therapist and Supervisor, currently based in France. She has been licensed as a psychologist in California since 2004, and has been involved in AEDP since 2012.  In addition to AEDP her background includes psychodynamic, Jungian and psychoanalytic approaches to psychotherapy. Prior to becoming a clinical psychologist, Hoai-Thu had a 20-year career in biochemistry and biophysics (Biophysics PhD from Stanford University). With her American, French and Vietnamese cultural roots she is fascinated by issues of culture, and how culture shapes our view of ourselves and of the world and what we take for granted; she brings this experience into her clinical and supervision work. In her private practice in California she worked with (among others) Silicon Valley professionals, people with international backgrounds and university students, in areas including trauma, multicultural issues, and spirituality and religion.  She provides therapy in both English and French.

She currently lives in France and is semi-retired. She delights in providing training, consultation and AEDP supervision in English and in French to licensed clinicians.  She sees her role as a supervisor to not just teach AEDP therapy, its perspectives and interventions, as well as integration with other forms of treatment,  but also to facilitate the professional development of her supervisees. Her goal is that each supervisee-clinician find their particular therapy style, in their own voice.
