The purpose of this study was to discover what families perceive as the benefits of participating in family volunteering; specifically service missions and the substantive impact the experience had on the families. A grounded theory approached was used. Five families were identified through a criteria-based snowball sampling technique. The data were analyzed using constant comparison. Based on the data analysis a core category emerged that encapsulated the result of the family service experience. The core category was coined, "family deepening." Family deepening encompassed the essence of the process the families in this study experienced. In order to achieve family deepening the participants in this study participated in a purposive, unique, shared, interactive, and challenging experience. Additionally, they experienced sacrifice. All these attributes appeared to contribute to the process of achieving a family deepening experience.
