Kelly is blessed to be a wife, mother of 8, grandmother of 5, and a convert to the Catholic faith.  For many years she has enjoyed organizing events that bring others to the faith.  She is now so blessed to use these skills in the Office of Priestly Vocations to organize events for potential seminarians and support the courageous men who are currently in seminary, as they discern a call to the Priesthood.
