Ms. Friesen was introduced to the ideas of Murray Bowen in graduate school in social work at the University of Kansas. She moved from Kansas to Washington, DC in 1978 to pursue her interest.

She became an administrative assistant in the Biofeedback Program developed by Dr. Lilian Rosenbaum and participated in the postgraduate training program. Her early exposure to biofeedback significantly influenced her understanding of Bowen theory and her early focus on the physiology of relationships.

She was appointed to the faculty in 1987. She was the director of the Postgraduate Program in Bowen Family Systems Theory and its Applications from 1990-2003. In 1994, she expanded her clinical work to include neurofeedback. This led her into the study of evolution and the development of the brain as well as how the brain, mind, and relationships operate in synchrony.

In 2005, she co-founded The Learning Space, a conceptual place where individuals have an opportunity to experience and challenge themselves in relationships through the integration of Bowen theory and neurofeedback.

In 2012, Ms. Friesen and Kathleen Wiseman created a program designed for experienced business professionals, consultants, and responsible family members. This program integrates Bowen theory and neurofeedback to challenge people to be more of a self in their family and work settings.

Ms. Friesen is also active on the Board of Leaders for Tomorrow, the organization responsible for making the Bowen Archives available to the world.
