I believe the church is called to be a vibrant, life-giving place where people can be saved, set free and strengthened to live in victory and make a difference.
– Pastor Thomas

Thomas Humphries
Lead Pastor
I have served in full-time ministry since 2003, and have been married to my amazing wife Amity since January 2005. Every day I am even more glad that she said “Yes!” We are blessed with 4 beautiful children, and loving God and having fun together is the biggest part of our lives!
Micah Barclay
Associate Pastor
I am a disciple of Jesus, husband, father, and minister of the gospel. I am passionate about seeing people from all ages and walks of life, to get to know the Lord in a real and personal way. It is my highest honor and privilege to get to reveal the Father’s love to everyone I come in contact with and make a Kingdom impact in the world in which we live.
My beautiful wife, Adrienne and I have been married since 2009 and have four adorable kids. I have attended Rev City since 2005, and Adrienne has attended for her entire life. We have served in many different roles and capacities at Rev City over the years, including youth ministry and the praise and worship team. Before joining the staff at Rev City, I worked several years in the mutual fund industry in one of the world’s largest financial transfer agencies. I did my undergrad at the University of Kansas and am currently working on my Master’s degree in Spiritual Leadership from the Kings University.
Outside of church, I love spending time with my family. When I need some alone time I love getting outdoors especially, hunting, fishing, hiking and camping.
Damon & Neva Hieb

Our passion is Marriage! We are sold out to help couples connect with Jesus and become all that God has created them to be, both individually and as a couple. We are committed to living a life that uses the gifts and talents that the Lord has given us to encourage people to know that with God’s help they can have the marriage they have always dreamed of.
We both have have been in serving in ministry since 1990: Damon as worship leader, life group leader, marriage ministry leader and he has a passion for missions; Neva in women’s ministry, marriage ministry and children’s ministry.
We have been have been happily married since 1987 and have four amazing kids and one incredible grandson! In our free time we enjoy gardening, traveling and spending time with family and friends.
Eddie Diaz
Executive Pastor
My passion is to encourage people to have a personal encounter with God, through Jesus Christ, and to help them discover their freedom and identity in Him. I am honored to serve as the Executive Pastor of Ministries, and my goal is to equip and release believers to advance the kingdom of God within their sphere of influence.
As a pastor I have served in ministry for 18+ years. In addition to my experience as an Executive Pastor, I have had an opportunity to serve as a Lead Pastor as well as an Associate Pastor and have had the honor to serve in almost every area of ministry within the church.
I have had the incredible privilege of being married to my wife, Beth since 1997, and together we have three amazing children, Brandon, Miranda and Camden, and our family dog named Rocky. Beth and I strive to provide a fun, honest and peaceful home, where everyone is encouraged to share their personal truth and receive God’s unchanging truth in love, all with a lot of laughter in the mix! Some of my favorite things are eating dark chocolate, smoking meat on the grill and playing and watching sports, in that order.
Beth Diaz
Children’s Ministry Director
Wife, mom, mentor, dream manager, sister, writer and friend are a few of the words that describe me. My passion is to help people, young and old and from all walks of life, discover who they are in Christ, find out what their purpose and calling is and encourage them to pursue the calling and passion God has put in them.
I am blessed to serve as the Ministry Connections Director, where I get to help people connect to the various ministries here at Rev City Church. As I meet people and hear their story, I look forward to helping them find their place in the Rev City Family.
My greatest joy is being married to my husband, Eddie, and watching our three adult children become all God has called them to be. In my free time I enjoy writing, spending time building relationships and hanging out with my family!
Chet Kueffer
Worship & Technical Director
I have a burning desire to see the church worship the Lord with authentic passion, anointing, and excellence. I grew up attending this church and began serving on the worship team when I was a young teenager. I had the privilege of joining the staff full time in the spring of 2016 and considerate it to be a tremendous privilege and responsibility to lead our congregation in worship.
I was born and raised in the Lawrence area and graduated from the University of Kansas with a degree in Communications. Post graduation I worked full time in logistics for a ready mix concrete supplier meanwhile simultaneously continuing to pursue music. Through music God has given me the opportunity to travel the country and work on a wide variety of projects – both live and in the studio.
I love spending time with my beautiful wife Elizabeth. When I’m not hanging with “Liz” I enjoy running, snowboarding, nerding out on music gear, and shooting sporting clays.
Nathan Hammer
Media & Marketing Director
It is my passion to see quality media be an advantageous tool in reaching people for Jesus Christ. Far too often, media is utilized in a way that hinders the Gospel. God has placed media on my heart since my freshman year in high school and He has graciously led me by the hand ever since. I’ve been blessed to attend this church for my entire life. Over the years I’ve always envisioned a strong and effective media presence taking root here. It has been an honor to serve and grow in this church body that has meant so much to me for all of my life.
After graduating high-school in 2007, I attended a two-year film and media internship in Texas. After returning to Kansas, I received my bachelor’s from the University of Kansas in Film & Media Studies, with a Minor in Business. I have been blessed to work for various Christian organizations over the past decade—utilizing media within all of them to help reach people for Jesus. Media can (and will!) be used to impact the Kingdom of God.
I could not do what I do without the help, love, support, and encouragement from my best friend and wife, Betsy. We have been married since 2012, and our two amazing boys (rambunctiously cute!) keep us active and busy. Being the church’s resident “media guy”, it’s probably a cliche that I enjoy all things media: editing videos, watching movies & tv shows, and having Hans Zimmer’s soundtracks looping on repeat. Like 90% of Lawrence natives, I enjoy watching KU basketball and exploring God’s beautiful nature around Clinton Lake. My heart is filled with so much joy spending time with my family and I wouldn’t trade it for anything in the world! The Lord has blessed me immensely and I am so thankful that I get to walk with Him each and every day. It’s my ultimate desire to pursue Him more, know Him more, and be changed by His love.
Mackenzie DeBoer
Elementary Ministry Coordinator
Constructing an environment for kids to feel welcomed, loved, supported, and encouraged in Christ is my passion. I want every child to experience radical transformation in the Lord and to know that they are a precious, cherished part of the kingdom of God. Watching a child get excited that they brought their Bible to church or that they remembered their memory verse, is a testament to what this ministry strives to accomplish. I am honored to walk alongside these children and to speak the truth, wisdom, and love of the Lord over them. That they might know who their Lord and Savior is and have an intimate relationship with Him!
I am originally from Michigan but came to Lawrence in 2017 to attend the University of Kansas. I happened to randomly visit Rev City years prior while in town for a tour of KU. I immediately knew that the Lord had brought me here for a specific purpose. I began to get plugged into the worship team and Rev City Kids ministry and saw the Holy Spirit alive and moving in the church! I graduated from the University of Kansas in December of 2020 with a Speech-Language-Hearing degree and hopes to eventually become an audiologist and work with children who have hearing loss. In the now, the Lord is calling me to help children hear in the spiritual realm and to listen to the calling Jesus has placed on their lives and I couldn’t be more excited!
In my free time, I love to spend time with friends as they have become my family here in Kansas. I also love to read – when they’re not textbooks for school – and have quite a large collection of books! Spending time outdoors hiking, hammocking, going to sporting events or just enjoying God’s beautiful creation is a blessing I never take for granted and always enjoy doing!
Caj Kueffer
Youth Worship Director
I am a passionate worship leader because I have a relationship with Jesus who has given me grace & the Holy Spirit to lead others into the Lord’s presence. Jesus made the greatest act of worship when He submitted His life on the cross. Jesus reveals how much our Heavenly Father loves us and makes a way for us to be a part of the family of God. What an awesome Heavenly Father we have!
My amazing wife Hannah and I got married in September of 2017 and we have one incredible son. We met at Rev City & now get to serve Rev City Youth (RCY) together with an incredible worship team & staff.
I enjoy spending time with my wife. Some of our favorite things to do together are fishing, cooking, swimming and wood-work projects. If I’m not at work or church I’m likely on a run or writing songs.
Amity Humphries
Communications Coordinator and Women’s Ministry Events
My heart and passion is for people of all ages, backgrounds and walks of life to be filled with confidence, joy and the vibrant life of Jesus Christ. God promises us in Ephesians 3:20 that HE IS ABLE to do exceedingly, abundantly above ALL we can ask or think through His mighty power. Through Him and Him alone, I have personally experienced God’s miraculous love, freedom, healing, acceptance and grace, and I desire to see all of His precious sons and daughters to receive the same!
I have been married to my incredible husband, Thomas since January 2005 and continue to fall more madly in love with him every day. Being a pastor’s wife since age 18, I have had the honor and privilege to serve alongside my husband in various roles. From cleaning toilets & answering phones, to serving & leading in areas such as Children’s Ministry, Youth Ministry, Worship, Administration and more. Currently my role at Rev City balances Women’s Ministry event planning along with church administrative/communication tasks. I absolutely LOVE organizing, writing, planning, making schedules and checklists – so I find great joy in this role!
Thomas and I are blessed with 4 beautiful and vibrant children. Our life is very busy and sometimes kinda crazy, but we strive to keep a healthy balance of serving the church, spending time as a family, working hard, playing hard and resting.
My favorite things to do include date nights with T on Mass Street, family movie time in our living room with LOTS of pillows and blankets and playing softball with my Rev City Sisters!
Laura Roth
Finance Administrator
Growing up I never saw myself working in ministry. The moment God radically touched my life, everything changed. I knew every single person needed to hear about Jesus and His amazing love; however, I wasn’t sure how He could use my skill set to make an impact for the Kingdom. God’s timing is perfect and I am grateful He chose me to walk this life with Him.
My hunky husband, Michael, and I have been married since 2011 and He has blessed us abundantly with three beautiful children: Breckyn, Asher, and Olivia. We walked through the doors of Rev City Church for the first time in August 2014, plugged in, and never looked back. This is our home. We hope you will find your home here as well!
I graduated from Fort Hays State University with my dual Bachelors of Business Administration in Accounting and Finance in 2008 and gained my certification as a Certified Public Accountant in 2010. Over the years, God has used me professionally in the public accounting world, as well as in the private industry of international construction. He has also used my giftings to serve on the Board of Directors for Big Brothers Big Sisters of Finney County.
In the majority of my time, you will find me with my family. It is such an honor to raise these three children to know, love, and serve God. We enjoy traveling, spending time outdoors, making memories, and helping my dad with wheat harvest.
Ashley Christline
Early Childhood Ministry Coordinator
I have a heart for children and letting them know that they have a heavenly Father who loves them unconditionally. Proverbs 22:6 instructs us to “Direct your children onto the right path, and when they are older, they will not leave it.” Children’s Ministry allows us to help instill Biblical values in children that will stay with them for the rest of their lives. As part of the Rev City Kids Team, my desire is to provide a loving, fun environment that is engaging for kids and also makes parents feel comfortable that their children are cared for and well loved.
I graduated from the University of Nebraska in 2005 with a degree in International Business. I’ve worked in the consulting/HR space as a project manager helping organizations measure and improve employee engagement in their workforce.
I have been married to my amazing husband, Cody, since 2005. We have 5 beautiful children ranging from preschool to middle school. We were both raised in Nebraska and spent 9 years in the Air Force before settling down in Lawrence in 2018. We started attending Rev City shortly after. We were initially drawn to the church because of the welcoming nature of the congregation. We quickly decided to make Rev City our church home because of the passion and conviction behind the ministry.
In my spare time, I love spending time with my husband and kids and our extended family which includes many siblings, nieces and nephews. I also love to travel, experience different cultures and enjoy the natural beauty God created.
Clint Kueffer
Elder
I have been attending the church for more than three decades and am the oldest of Steve and Pam Kueffer’s 9 children. My wife Sarah & I were married in the church in 2004, have assisted with Alpha for several years, have served as deacons and I have been an Elder since 2014.
Prior to serving as Elder, I played guitar on the worship team for approximately twenty years.
My wife & I own and operate an independent insurance agency – Integrity Midwest Insurance. When not at work or church, I love spending time with my amazing wife Sarah, our wonderful children and all of my brothers and sisters. When I’m not spending time with my family, I might be trying to beat Pastor Thomas at golf… a feat I admit may not happen before Christ’s return.
Terry Marshall
Elder
I have been married to my beautiful wife, Kathy for 47+ years and we have 3 daughters, 2 sons in-law and 4 fabulous, active grandsons. We have been attending this church for 35 years & have served in many capacities during this time.
My desire is particularly to help people discover & understand God’s purpose for their lives, and to pursue their purpose with passion. Kathy & I both are both excited about the direction the Lord is leading Rev City & enjoy interceding in prayer to see God’s purpose accomplished.
I am in the aerospace industry & currently am President of a small, local Aeronautical Engineering services company. I enjoy traveling & playing golf.
Thomas & Amity Humphries
Pastor
I have served in full-time ministry since 2003, and have been married to my amazing wife Amity since January 22, 2005. Every day I am even more glad that she said “Yes!” We are blessed with 4 beautiful children, and loving God and having fun together is the biggest part of our lives!
Early in 2015, we heard the Lord tell us to prepare for transition. In faith, we resigned our position at a wonderful church in a beautiful part of Texas and began to pray. We sensed the Lord tell us that He had asked us to become unattached so that we could be part of His answer to the prayers of a precious group of people that were beginning to walk through a leadership transition. In the summer of 2015, the Lord connected us to this church and brought numerous confirmations that we were to move our family to Lawrence to serve this church, city and region. Because we are passionate about Jesus, we are passionate about people! We have a strong desire to see every person discover the life-changing love, forgiveness, freedom, and empowerment of God in a way that helps them live abundant, adventurous, and courageous lives of faith! We are honored and humbled to serve, and are very excited about the future of the church and all that God desires to do in Lawrence and the surrounding area! If we haven’t already, we hope to meet you soon!
Above all, I love to spend time with my family. I also enjoy golfing, fishing, and playing sports with friends! I’m a life-long Dallas Cowboys fan, but it’s been easy for me to quickly root for all teams Kansas! The moment of truth for me will be if and when the Cowboys and Chiefs play in the Super Bowl!
