Women of Providence in Collaboration or WPC is an association of congregations of North American Roman Catholic religious sisters with "Providence" in their name. It initially grew out of an idea by Sister Michelle Holland, SP (Spokane, Washington), to have an event for religious congregations to come together with the purpose of "exploring together the theology and spirituality of Providence." This event occurred in 1980 in Great Falls, Montana, and 80 sisters from varying congregations attended.
