Rev. Mike Erdman

Mike Erdman was born in Scottsbluff, NE, in 1982. At 18 years old, he moved away to Laramie, Wy to start college and decided that he would live out the story of the prodigal son. 


Many years were running away from God and doing his own thing until one day; he met a man who started to show Michael the love of Jesus through it all in Douglas, Wy. Michael began to study the Word and to learn who Jesus is and began to enter into the community of a local church in Douglas. He met a beautiful woman named Jamie, who eventually became his wife and started walking through the healing process. Together they have five beautiful and challenging children.


Michael started to say “yes” to Jesus in little ways, starting with volunteering on the worship team to play bass at the Gathering in Douglas, stepping into youth ministry, and helping with events. Small, simple things God has asked him to do have become stepping stones to lead him to the next place that God is leading, and that ended up being back home in Scottsbluff, NE, at the Rock as the worship pastor. I’ve never looked for the positions that I have, but God keeps leading me, and I pray and ask for His advice in all things, and He never ceases to amaze me in His plan for my and my family’s life.


I still have much to learn, and I know that God is always showing me who He is, but I am excited to see that He is doing great things. I Praise God for what He has brought me out of and for where He is taking me. God is Good!

Angie preston

Angie was born and raised in Scottsbluff. In 2007, she graduated from Hollins University in Roanoke, VA. After a short stint in New York state teaching Environmental Education, she and Travis got married in 2008 then started their life together in Hawaii, moved to North Carolina and then Illinois. After their daughter Nora was born, Travis received an excellent job opportunity, and they moved back to Scottsbluff and to be closer to family. 


Angie never thought a position in ministry was in her future, but after serving in KIDZ Rock, God moved in her to begin working for The Rock Church. Angie is passionate about intergenerational education and mentorship and sees the power of learning through experiences. God is stretching and molding her beyond what she ever thought was possible, and she’s excited to see what God has for her in the upcoming years. 

Antonio Cortez

Antonio was born and raised in Scottsbluff. In 2020, he graduated from Scottsbluff High School. While in high school, he participated in many events, such as band, choir, show choir, musical, and orchestra. 


Antonio comes from a family of ministers and has the heart to serve. The Lord called him to The Rock Church in 2018 to volunteer on the worship team, and he has been dedicated ever since. 


“I am excited to see what God will do not only in my life but the lives that I meet along this journey.” 

Jacob Crotsenberg

Jacob Crotsenberg grew up in Cheyenne, Wyoming. After living in Laramie, Wyoming, for almost six years, he took a job opportunity in Scottsbluff in 2019, believing he would only be here for two years or less. Thankfully, the Lord had different plans for him and called him to serve in ministry here in the Valley.


Jacob loves music, food, sports, and working out. He spent five years in ensembles in college, which gave him many opportunities for travel and leadership, four years in the restaurant industry, four years of high school sports, a lifetime of fandom for the Green Bay Packers, and has recently gotten into fitness, and tries to go the gym every day.


Jacob is passionate about unity and organization within the workplace, equipping young people to lead the next generation, and hopes to influence many lives in the area to come to know Christ as their Savior.
