Greg Wheatley
Music Director

Greg Wheatley says that some of his earliest memories of music were of learning to play the piano under the instruction of his grandmother. From that point on, he can’t remember a time when there wasn’t music of some kind in his life. After graduating from high school, he attended Spring Arbor College, where he earned a degree in music. He eventually went on to earn a Master’s degree in music theory from Michigan State University. Along the way, Greg’s involvement in Christian broadcasting brought him to Moody Radio, where he spent 22 years. His interest in broadcasting combined with his love of sacred music resulted in the program Sound of Majesty, which aired on Moody Radio for most of those 22 years.

Greg has considerable experience in choral conducting. He is the musical director of the Glen Ellyn-Wheaton Chorale. He has also served as the director of the College Church Singers and as one of the interim directors of music at College Church. He serves on the adjunct faculty at Wheaton College.

Tatum Yancey
Office Administraor

My path so far has led me to many different professional workplaces. From the summer of 2016 up until December of 2019, I worked in the professional film industry in Chicago, mostly as a set dresser and props buyer. However, at the start of this year, God confirmed that it was time for me to pursue full-time ministry in Spain. With my partnering organization, I will be ministering to the people of North Africa. Amazing work is being done already over there, especially during these COVID times, and I can’t wait to be a part of it!

I am so blessed and grateful that God has provided me the opportunity to serve the church here as I continue to raise support. I hope to get to know many of you in the coming months. If you talk to me about film, Jesus, music, or traveling, we will definitely be friends!
