Ketly and Vital work in the East Coast of the Dominican Republic to strengthen local churches and encourage existing churches to plant new ones and disciple new members. One way they do this is by leading and coordinating seminars and workshops. Through these sessions, pastors and leaders of local congregations learn how to start and strengthen a broad range of outreach ministries in their communities. The Pierres also serve as a link with volunteer groups, matching them with local ministries according to where they would be the most effective, and encourage and facilitate Haitian mission work both within the D.R. and abroad.
