Jana Vinsky MSW, RSW is the co-founder of Liberational Practice International (LPI) Inc. www.lpimodel.com

Jana has been supporting organizations for over 30 years to meet human rights standards. She also taught nine social work courses at Toronto Metropolitan University and was the Anti-Oppression Practice Lead for a large child welfare organization.

Jana worked as a social worker in frontline, management and on a provincial level where she led the development of a service delivery model to address disproportionality and disparities facing African Canadians in child welfare. She led the development of a program that helps match Black children and youth in foster care with adult "aunties and uncles" from their communities to help youth stay connected to their culture and learn life skills relevant to their social context. Jana also developed the Equity Integration Advisory Group at the Ontario Association of Social Workers, which was pivotal in the monumental transformation of the organization.

She is trained in Narrative Therapy through a three-year externship program, where she advanced the LPI model. She is a certified Shame-Informed Treatment Specialist (CSTS) and clinical traumatologist. Jana believes human rights education is best done with a shame and trauma informed approach. Jana has The Osgood Certificate in Human Rights for Education Professionals and the MIT Advanced Certificate in Applied Human Rights.
