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. (more…)

Barbara J. Suter, PhD

Barbara J. Suter has been a clinical psychologist for over 40 years, practicing psychodynamically and experientially oriented work with individuals–child, adolescent, adult–and with couples, families, communities, schools and other agencies.  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, finding that AEDP uniquely lends itself to therapy, supervision and front line helping people in their communities and families.

After AEDP training in the early 2000’s she became deeply interested in understanding and working with the body in psychotherapy and trained for three years with Dr. Peter Levine’s Somatic Experiencing approach to become a practitioner. She has found combining AEDP and SE 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. Dr Suter has taught and supervised in (1) George Washington University PsyD program (2) The Washington School of Psychiatry Intensive Short-Term Dynamic Psychotherapy program and their Supervision program, (3) A Clinical PhD Social Work program in Washington, DC. and (4) consulted with both public and private schools in the Washington, DC area and (4) a domestic violence program training counselors to do psychotherapy with their clients.  She maintained a private practice in Washington, DC until covid and now works remotely via zoom from Virginia. She is licensed as a clinical psychologist in DC, Maryland, Virginia and Vermont
