Bernadette O’Koon

Leadership Team

Bernadette (“Bernie”) O’Koon, is a 5th year Clinical Psychology doctoral student at the School of Professional Psychology at Wright State University in Dayton, OH and is completing her internship at the University of Pittsburgh Counseling Center. Bernie is a “recovering lawyer” whose chance exposure Gestalt in 2007 was the catalyst for deep personal and professional exploration and an eventual mid-life career change. Bernie trusts in the therapeutic process and believes that profound growth is possible when we understand our personal experience and development within the context of political and social systems and within our own bodies.

Toni Clarkson
U.K. |
Leadership Team

Toni loves chickens, gestalt, coaching, leadership, mountains and gardens. The order of those changes, but they never go away. Toni cares very much indeed about the quality of conversation we are able to have with ourselves and with others, and our willingness to hold our own truths and those of others with kindness. “And you can put I’ve got an international corporate OD background if you want!”

Kamila Bialy
Poland |
Leadership Team

Kamila is a sociologist and gestalt therapist in one! When she works as a therapist, her sociological eye is always present, and often alert/activated/activist -oriented. As a sociologist she applies a relational field perspective. Having lived and practiced on the margins Kamila now also holds formal positions within academic and gestalt therapy worlds. She wonders, does this say more about her, or about the world she lives in?
