Andrea McMahon

She is blessed to be part of the Family Promise Team, creating a space for the community to support families and to see families move from surviving to thriving. Andrea is wife to the amazing Andy and mom to 3 wonderful children. They live in Lawrenceville and aim to serve the Lord in all they do!
