As Director of Children’s Ministry, Erin desires to partner with parents as we teach our covenant children about Jesus.  Relying on the Holy Spirit, we disciple our children as their understanding grows. Erin is eager to equip parents, teachers, and volunteers to teach our littlest through elementary-aged children about God’s extraordinary love and model what it looks like to love Him and love others because of the gospel.

Erin loves children, reading, and a cup of good strong tea, as well as kayaking and exploring with her husband, Ryan, and son, Graeme.

Adam LeRoy

Director of Youth Ministries

Adam oversees APC’s ministry of bringing the light of the gospel to teenagers, both inside the APC family and in our surrounding community.  He desires to see a growing community of teenagers trusting in Jesus and being transformed in the places where they are hurting most, right where they are, just as they are!

God has been opening doors for Adam to work with teens since his college years at JMU, and he has been on staff at APC since 2005.  Adam and his wife Laurie were married in 2001, started attending APC in 2002, and have five children — Mella, Dante, Brody, Asa, and Miles.  They are both blessed to be in service to the King here in Alexandria!

You might find Adam passionately managing one of his boys’ baseball teams, whistling/tapping along to music while he works (on good days), packing his car up to the brim at Costco, or soaking in as much summer sunshine as he is able.
