Kate Halliday, LCSW

Kate Halliday, LCSW, is Senior Faculty, AEDP Institute from Ithaca, New York.

Throughout Kate’s nearly 30 years as a psychotherapist, She has always been better at noticing the ways her clients are remarkable, resilient, and lovable than theorizing about the ways they are wounded.

Kate has always been drawn to images, representations, and experiences of transformation. Music, poetry, literature, the natural world, and emotional relationships have always been her education. When Kate started learning to be a teacher of young children (in her first career she worked for Head Start and in elementary schools), and then to be a therapist, it was the magic of witnessing change and growth in other human beings that enlivened the experience for her. In psychotherapy, this led Kate to study Family Systems Theory and Narrative Therapy, then EMDR, and finally AEDP. (Read More…)

Barbara J. Suter, PhD

Barbara J.

She is involved in training both new and experienced therapists. A lifetime of a rich, rewarding experience helping people has culminated in experiential work: through AEDP, and its holistic, healing, helpful approach, Dr. Suter has found a way to integrate many decades of previously disparate experiences. Dr. Suter has found that AEDP uniquely lends itself to therapy, supervision and front line helping people in their communities and families. She has found it particularly useful with those suffering from trauma, reeling from life, and unable to find help despite a long time of seeking help, healing and change. (Read More…)
