Tom and Vicki Gilliam are based in the Republic of Ireland and reside in Maynooth, County Kildare, a university town of 16,000 located on the western outskirts of Dublin, Ireland's capital. They are a part of the core group of Maynooth Community Church, a church they helped to plant and have ministered in since 2003.

Tom serves as an elder in the church and is involved in leading worship and discipleship. Vicki's passion for women sees her in discipling relationships across the age spectrum-from teenage girls and university students to women in their twenties, thirties, and beyond.

The Gilliams lead Serge's Dublin-based Leinster Team which supports and encourages Irish pastors and church leaders in their church planting and church renewal efforts in a variety of denominational and non-denominational contexts.
