The Grandparents Raising Grandchildren (GRG) Program of Pittsburgh, a service of the Sisters of Mercy of the Americas, began in 2010 as a monthly support group where grandparents could share their needs.

It will soon open its third site on the Mount Alvernia campus of the Sisters of St. Francis of the Neumann Communities in Millvale. The Millvale GRG will be a collaboration of the Franciscan and Mercy sisters.
