Discipling children to know and love Jesus, understand God's Word and show Christ-like character has always been at the heart of the calling God has placed on Ivy Adair's life.
Outside of ministry, Ivy Adair enjoys listening to music, getting lost in a good novel, relaxing with a color-by-number book, spending time with friends, and making memories alongside her husband, Corey and newborn baby boy, James.
Zander Turner
Student Pastor
zander.turner@prestonridge.org
Zander has served as the Youth Pastor at Preston Ridge Church since August 2024. His passion is to see students know and love Jesus, grow in their faith, and become lifelong disciples who make disciples wherever God leads them. A driving vision for Zander’s ministry comes from 2 Timothy 2:2: investing in faithful people who will be able to teach and lead others. His desire is to build a student ministry where students are not simply consumers of ministry, but are equipped to lead, serve, disciple others, and carry their faith beyond their time in the student ministry.
Zander grew up in the small North Texas town of Gunter, Texas. After graduating from Gunter High School, he attended Kanakuk Link Year before serving with a college ministry in Fayetteville, Arkansas. He later returned to Kanakuk to serve as a Link Year Shepherd, where he had the opportunity to invest in and disciple college students.
Outside of ministry, Zander is a sports fanatic and lifelong Dallas Mavericks fan. He will rarely turn down a pickup basketball game and enjoys just about anything that involves competition, friends, and a good time.
Zander is engaged to his sweet fiancé, Sadie, who is from the Frisco area. Together, they are excited to build their life and make North Texas their long-term home.

Worship Minister & Technical Director
Nolan.Stone@prestonridge.org
Nolan joined Preston Ridge as our worship leader in January of 2026. Nolan has served in worship ministry for over eleven years. After coming to faith in Christ at the age of eighteen, the Lord gave him a deep desire to proclaim the gospel through congregational singing—a calling that has shaped his life and ministry ever since.
Nolan studied Worship Leadership at Dallas Baptist University, where he met his wife, Alexis, who also shares his love for serving the local church through music. Together, they are passionate about seeing the church treasure Christ through worship that is rooted in God's Word.
Nolan is committed to leading the church in songs that exalt the glory of Christ, faithfully proclaim the truths of Scripture, and encourage the congregation to sing with both conviction and joy. He believes one of the greatest privileges of the Christian life is gathering with the bride of Christ each Lord's Day to declare the finished work of Jesus through biblically rich, gospel-centered worship.
