Lead Pastor


I previously served for 5½ years as Associate Minister of the Missouri Valley Christian Church (1984-1989), where I also coached AYSO soccer, freshman boys and girls basketball, and started a Fellowship of Christian Athletes.

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. Eventually, I started coaching softball and teaching algebra in the local public high school, but God used that experience to transform my life and ministry.  He opened the door for me to return to Thunder Mountain, and this time 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!

A trial emerged late in 2011 when a growth in my tongue was discovered to be a malignant tumor.  Approximately 40% of my tongue was removed and rebuilt using the tissue from my wrist.  Two other tumors were removed from my neck in the initial surgery and another was discovered after the completion of radiation and chemo requiring a second surgery on July 2, 2012.  Initially, the doctors said that it might take a year to be able to speak clearly again, but I preached on the first Sunday of February 2013 and returned in April to regular preaching duties.

Kim and I were married in 1984. We have two grown and married daughters who serve the Lord with their husbands, and four grandchildren.

I received my bachelor of arts in Pastoral Ministry from Nebraska Christian College and my master of arts from Cincinnati Christian Seminary.

Executive Pastor


Before coming to Thunder Mountain in January 2012, I was a 9th grade Social Studies and English teacher at Catalina Foothills High School in Tucson.  I first got involved in Student Ministry and Worship Arts Ministry back in 2005 in Tucson when I started leading a small group and playing guitar on Wednesday nights.  I held a variety of jobs over the years ranging from frying chicken, making sub sandwiches, scooping ice cream, preparing coffee as a barista, and running an after-school program for 7-year-olds.

Currently, I serve as the Executive Pastor. In this role, I partner with our Next Gen. Ministry Pastor and Connections Pastor to create environments where people can experience the transforming love of God!  I also teach at our weekend gatherings about once a month.

My beautiful wife, Eileen, is a scientist and middle school teacher turned stay-at-home mom with our sons, Sean and Levi, and daughters Grace and Mykah.  We met in a high school history class in 11th grade and were married back in 2008.

I graduated from the University of Arizona in 2009 with my bachelor of arts degree in History for Secondary Education.  I also received my Master of Arts in Ministry Studies from Grace College and Theological Seminary in 2014.

 Fun Facts:

  • I play an assortment of stringed instruments including the guitar, ukulele, and mandolin.
  • I own enough plaid, snap button western shirts to wear for 3 weeks consecutively, without repeating.

Next Generations Pastor

Twitter: @9adam_holl

Before Thunder Mountain, I met my beautiful wife, finished up my college education, and was an intern at five different churches.

As the Next Generations Pastor, I get the opportunity to work with the kids and teenagers at Thunder Mountain Church and in the community of Sierra Vista. I think it is great to be able to work with both age groups because we can really partner with parents and push the kingdom of God forward long past our own lives.

My wife is the funniest person I have ever known. I met her at college and she finished up her degree to lead worship and has the most incredible voice, but her love and compassion are what has made her my best friend.

I attended Nebraska Christian College and have received my Bachelor of Arts in Pastoral Ministry with an emphasis in teaching and preaching. I’ve gotten to work with multiple youth groups before leading high school and small group studies and built a children’s ministry in the church that I grew up in back in Colorado.

Fun facts:

  • I love coffee. It’s really a problem. Like, I quit cold turkey once and got extremely sick. (I have cut back a lot since then.)
  • I can, and happily will talk about comic books for an embarrassingly long time.

Connections Pastor


I moved to Thunder Mountain Church from my home state of Texas where I worked in accounting, oil & gas, customer service, and multiple churches in full-time ministry. 

In my role as the Connections Pastor, I will oversee the guest experience and Connect Groups. I love to make guests feel valued and welcome and I'm passionate about helping people plug into authentic community. 

I'm proud and grateful to call Ashley Chapman my wife, adventure buddy, and Netflix-watching teammate.  

I received my BBA in Accounting from Midwestern State University and my Master of Divinity from Southwestern Baptist Theological Seminary. Years of service in the church world in volunteer and staff capacities, as well as leadership development from Watermark Community Church and Cross City Church, prepared me for this opportunity.

Fun Facts:

  • I've biked down a volcano and have been bitten by a tiger. (Well, a baby tiger, but still.)
  • I'm always down to try new food, play board games, or watch/play soccer or volleyball.

Stewardship Director


Before becoming the Stewardship Director for Thunder Mountain in 2016, I was a teacher, assistant principal and principal at Buena High School.

I feel strongly that giving to the local church is something we are commanded to do biblically and something that is a vital part of our spiritual growth and the growth of Thunder Mountain. I am continually encouraged to see how God uses the generosity of the people of Thunder Mountain Church for His glory.

I was born in Missouri as the fourth of six children.  My family moved to Tennessee when I was one, where I spent the next eighteen years before joining the Army.  I met my wife (Gail) at Ft. Devens, Massachusetts where we were later married.  I served just over twenty years in Army intelligence as a Morse code interceptor, retiring as an instructor from Ft. Huachuca in 2004.  I spent the next twelve years in teaching and administration at Buena High School and retired in June 2016.  

My wife and I have been in the area since 1997.  We have three adult sons and five grandchildren.

I have a Bachelor's in Criminal Justice, a Master's in Education Administration and a Master's in Financial Planning.  I have also completed the Financial Coach Master Training through Ramsey Solutions.  My wife and I have facilitated numerous finance classes and provided financial coaching to several folks here at TMC.

Fun Facts:

  • Although I have been bungee jumping and rode the Sky Coaster at Royal Gorge, CO, I am afraid of heights.
  • My wife and I enjoy using our RV to travel and minister across the U.S.

Before coming to Thunder Mountain, I worked at Cochise College in the Business Office, where I had just reentered the workforce after taking a few years off to focus on my family.  Before that, I worked as a part-time accountant for 13 years at St. Joseph Medical Center in Bellingham, WA.  I also volunteered at my kids’ school, with their extra-curricular activities, and in our local church.

I am currently Thunder Mountain’s Accountant, where I ensure timely and accurate processing and reporting of the church’s financial records. I am committed to maintaining confidentiality and helping the church be the best steward of the resources God has given.

My husband, Leon, and I were married in 1995 and have been blessed with 2 beautiful girls, Haley and Nessa. Family time is a necessity for us and we try to make sure we get enough of it with everyone’s busy schedule.

I graduated from Western Washington University in 1999 with my Bachelor of Arts in Accounting. 

Fun facts:

  • I enjoy hiking, running, walking, anything that gets me outside. Nature is my therapy. My family often gets forced to participate in my shenanigans.
  • I received the nickname, Crash, in high school, after multiple fender benders (one involving backing into a tractor in our driveway).  But, I’m happy to say my driving record has been free and clear of any accident since my teenage years...but don’t ask me about speeding tickets.

Go Hawks!

Facilities Readiness Ministry Lead


Before working at Thunder Mountain, I worked mostly retail. I worked my way up at Wal-Mart from a Sales Associate to Zone Manager and was the Safety Team Lead for the store. I also managed a couple of Circle K stores before that.

I spent some time doing a hotel renovation in Phoenix, AZ, which taught me a lot about general construction, groundskeeping, and plumbing.

As the Facilities Readiness Ministry Lead, I do anything in my skill set that helps to maintain and improve the church facilities. This includes setting up and breaking down any events held at the church and making sure that the buildings and grounds are clean and welcoming to any guest that decides to visit us.

I have a beautiful wife and four amazing children who never cease to amaze me with their kind, loving and generous hearts.

Fun facts:

  • I love Martial Arts and have been practicing Wing Chun Kung Fu for over a decade; teaching it from home since 2015.
  • I played the trumpet in high school and was in a marching band, symphonic band, jazz band, a mariachi band, and my youth church praise and worship team.

Next Generation Resident


Before coming to TMC, I was a student in college and served as the Kids’ Director at Heritage Church in Round Lake, IL.
