In the early 1970s Rosen became totally immersed in the movements of the time. She joined with other political activists to form Centers for Change (CFC), a collective of health, educational and political liberation centers organizing in poor and working class communities. The group began building new kinds of institutions: free schools, community-based health clinics and psychotherapy centers. This was the start of her career as a helping professional, and the beginning of her training as a Social Therapist.
