Our Team
Richard Mullen
Lead Pastor
Bold and courageous, Richard Mullen is one of the founding pastors of Cornerstone Church. He holds a B.A. in Sociology from Baylor University and serves on the board of FCA Urban Atlanta. His years living in Saudi Arabia and traveling the world have contributed to his global perspective, visionary leadership, and spirit of servanthood. His near decade in ministry has included lay pastoring, church planting, and consistent service to others.
Through it all, he’s navigated difficult communities to see the Gospel spread. A loving husband to Amanda and father to Micah, Jaeden, Amaya, Aaliya, and Aida, Richard can be found flexing his skills in the kitchen, putting his green thumb to work in the garden, or perhaps reminiscing about when he played in the Little League World Series in 1997.

Sandra Mitchell
Kids Director
Sandra Mitchell is the Kids Director at Cornerstone ATL. With over twenty years of experience working with children and families both in the school system and in youth ministry, Sandra’s teaching experience and love for God and the Bible allow her to serve her community and care for others well. Sandra’s welcoming spirit makes it easy for her to connect.
A self-proclaimed “Bible nerd,” she has a Scripture or a Biblical account that speaks to most situations, a gift she’s honed over the past twenty years through long-standing participation in Bible Study Fellowship (BSF). Sandra is known for wearing her heart on her sleeve—and for verbally processing her way through all the books, podcasts, and documentaries she consumes. A lover of life’s simple gifts, Sandra’s greatest joy is her family, including husband Damian and their five children.

Of all his accomplishments, however, Moe’s pride and joy are his two boys Josiah and Elisha, his daughter Josephine, and his lovely wife Sandy.
