Karen Clifton is the founding Executive Director of Catholic Mobilizing Network (CMN). She began her work against the death penalty in 1996 in Houston, Texas, when her social justice and advocacy projects intersected with those of Sr. Helen Prejean, CSJ. This relationship resulted in the 2008 formation of CMN in partnership with the Congregation of St. Joseph Sisters.
She is now the executive director for the Catholic Prison Ministries Coalition (CPMC).
