My wife and I went on a Catholic Engaged Encounter weekend in March of 2007, and began to volunteer our time 3 months before we were married, and we've been involved ever since. We have been a prayer couple, hosting team, presenting team, local coordinators, and the social media coordinators for the National organization.
This is a great non-profit dedicated to making sure that couple receive the tools they need before getting married to lower the divorce rate.
