Devoted to a God-given passion for The Church and its responsibility to start new churches—churches specifically designed to reach out to children at physical and spiritual risk—Greg Nettle serves as President of Stadia Church Planting. As a visionary and catalytic leader, Greg has led Stadia from planting a handful of churches to planting more than 350 churches around the globe in 2020.

Prior to his time at Stadia, Greg served as leader of the RiverTree Movement in Ohio for 25 years. His sense of adventure has taken him around the world as he has climbed Mount Kilimanjaro, Cotopaxi, and Whitney (among others) to raise funds to bless children on the margins of society.

Greg’s most important partner in life is his wife, Julie, as they lead their children, Tabitha and Elijah, to fall deeply in love with Jesus. He is an author, speaker, and consultant as an agent of change in the global church and has co-authored three books: Small Matters, in collaboration with Compassion International President Jimmy Mellado, One Of, and Disciples Who Make Disciples.

Tim Celek lives in Costa Mesa, CA with his wife of 40+ years, Sue. In 1988, Tim planted The Crossing Church, and over 30 years had the opportunity to see the Crossing grow, reflect, and impact the coastal community of Orange County. On the church’s 30th birthday, Tim intentionally handed off leadership of The Crossing Church. During Tim’s tenure, The Crossing Church resourced 5 new churches, which makes Tim’s role of Senior Director of New Church Growth with Stadia (www.stadia.org) the perfect fit for this Harley-loving church planter. Tim enjoys sailboat racing, and when he isn’t on boats or motorcycles, he loves to spend time biking and building Legos with his grandsons (and their moms, who happen to be Tim’s daughters.)
