Part of PACT brain trust – collaborating with Dr. Stan Tatkin in developing of curriculum and trainings. Dr. Hans Stahlschmidt is an experienced therapist who works with couples and individuals in private practice in Berkeley, CA. He is interactive and direct and, from early on, establishes a secure frame that allows the couple to be vulnerable as well as rise to the challenges necessary for lasting change. He calls his office a “failure-friendly space.”

He believes that navigating a primary relationship is one of the most difficult human endeavors but also one of the most rewarding ones — a challenge that will make us grow. For Hans, it is a privilege to be invited into the most intimate aspects of the lives of his clients. He loves life stories and the way individuals discover how to cope, manage, and survive, often in unimaginably difficult situations. The challenge of couples work is to transform what has served well in the past into a healthier and more effective way to relate to oneself and to others.

Hans has studied, worked, and taught in Germany as well as in the United States. He holds a German psychology degree from the Freie Universität Berlin and practiced in Berlin as a licensed psychologist. He received his PhD from Pacifica Graduate Institute in Santa Barbara, CA. While drawing upon a range of psychological approaches, he has made the PACT model his theoretical and practice-related home.

In his “former life,” Hans was a shiatsu teacher and body worker. He sees himself as well grounded in the practical world as a building contractor who has run a successful business for 25 years. His varied life experiences, including working in different professions and living on different continents, helps him establish authentic and meaningful relationships with clients from all walks of life. He loves hanging out with his two granddaughters and dancing tango. When he can find the time, Hans likes to write and paint and hop on his motorcycle for a ride through the Berkeley Hills and beyond.

As a PACT instructor, Dr. Patricia Hart brings to the PACT Institute more than 35 years of experience in individual and couples therapy. She also has a deeply held belief that fulfilling relationships are the central component of growth and healing. Her interest in the workings of the human mind, a call to attend to the suffering of others, and a belief in the healing power of a caring and empathic relationship led to her life’s work as a clinical psychologist. In her Berkeley office she helps couples develop the closer connection and greater security that will lead them to deeper intimacy and the capacity to more effectively address their challenges.

Patricia received her undergraduate and graduate degrees from Columbia University and her doctorate from the University of Hawaii. She has worked in many settings providing individual, family, and couples therapy as well as training and consultation on divorce and remarriage. She has trained in multiple therapeutic approaches including psychoanalytic, emotion-focused, and trauma-informed psychotherapy as well as couples work based on both attachment and differentiation models, including Gottman and Schnarch’s Sexual Crucible. Since hearing Stan Tatkin present in 2009, PACT has become her primary focus of training and practice.

She teaches secure-functioning principles for the PACT Institute and models them with her husband, Hans Stahlschmidt, who is also a PACT instructor. The oldest of Patricia’s three daughters is a PACT therapist who brings her acting skills to PACT demos. Time with her husband and growing family, piano, dance, skiing, hiking, and swimming in the freshwaters of Cape Cod ponds are her great pleasures.
