Randy Youngblood

Founder & Lead Pastor
I am the Founding and Senior Pastor of Thunder Mountain Church.  My wife Kim and I came in 1989 from Iowa to join with a few families who were looking for a different approach to doing church and reaching this generation for Christ. God called me not to grow a church but to grow people and to see salvation not just as something that occurs when we die, but a blessing to live out daily as citizens of the Kingdom of God!

Justin McPeak

Executive Pastor
As the Executive Pastor, I partner with our Pastoral and Support Staff to create environments where people can experience the transforming love of God, as well as rotate teaching at our weekend gatherings. My beautiful wife, Eileen, and four kids have been in Sierra Vista and part of TMC since 2012.

Tessa Galindo

Assistant to Lead Pastor
As Pastor Randy’s Assistant, I make it my mission to help him stay on task and to accomplish every goal that he hopes to reach. My desire is to help him do everything that God has called him to do and to build the Church to be what God always intended it to be. 

Graham Yost

Discipleship Pastor

Jeff Brundidge

Next Generations Pastor
As the Next Generation Pastor, I have the privilege to share the hope I have in Christ and do life with students.  I get a front-row seat in watching Jesus become number one in a student’s life.
