Who has made us competent to be ministers of a new covenant, not of the letter but of the Spirit.
For the letter kills, but the Spirit gives life. 2 Cor. 3:6


Scott Pearson

Pastor Scott has been married to Beth since 1974. They met at the University of Iowa at a Campus Crusade for Christ retreat. After marriage, they moved to the Twin Cities where Scott attended Bethel Seminary and graduated with an M.Div. in 1978. Beth also earned a Master’s degree during those years.

Scott pastored Ely Baptist Church near the Boundary Waters Canoe Area Wilderness in NE Minnesota from 1978 until 1991. Their three daughters were born in Ely: Erika (1980), Jill (1982), and Emily (1984). Those were wonderful years raising a family and serving a loving congregation in a beautiful setting of God’s creation. The Pearson girls benefited from growing up in such a beautiful and loving environment nurtured by such a wise and devoted mother.

Scott pastored Grace Baptist Church in Tracy, CA from 1991 to 1994. Those were hard years that ended painfully. Scott learned some hard lessons from some financial failures and painful experiences and took with him to Iowa a saying that is repeated following every Communion service at Cornerstone: “I am totally accepted, fully pleasing, deeply loved, completely forgiven, and empowered to live a new life in Christ because of the Cross and Resurrection of Jesus.”

Scott and Beth and family moved back to Davenport, Iowa (where Beth grew up) in the summer of 1994 – hurting and without a job. God graciously led this “vulnerable family” to Cornerstone shortly thereafter. “After great pain, a new life emerges.” The Pearsons have thrived at Cornerstone and in the North Scott area and are grateful for God’s abundant blessings.

The Pearsons have three daughters and 15 grandchildren, ages 12 and under.  Erika and her husband, Kyle, live in Arvada, CO, where Kyle is Lead Pastor of Revive Church.  They have six children.  Jill and her husband, Peter, live in Hayward, WI, where Peter works remotely as an engineer for John Deere.  They have five children.  Emily and her husband, Mike (Mo), live in Ames, where Mo is a CrossFit trainer and manager.  They recently returned from 10 years as Christian workers in SE Asia.  They have four children.


Mark Zevenbergen

Pastor Mark & Andrea are originally from Oregon where they began dating the last term of their senior year at the University of Oregon. After getting married in 1993, they moved to Chicago where Mark attended Trinity Evangelical Divinity School in Deerfield, IL. Following graduation with an MDiv, they moved to Iowa and have been serving at Cornerstone since 1998.  Mark served as the Associate Pastor until 2013, when he and Andrea planted the campus in DeWitt.  Since 2013, he has been ministering as the Campus Pastor.  Mark & Andrea are thankful to be part of the Cornerstone family that celebrates people coming to Christ and loves to serve their communities.

Mark & Andrea are blessed with three children-Jackson, Mac and Lynden and a silver Lab named Cascade.  Mark values getting away with his family on regular vacations.  He loves the outdoors and enjoys hiking, camping and fishing.  He is a life-long learner and an Apple enthusiast. 


Drew Webb

Pastor Drew has been married to his wonderful wife, Luvy Ann, for nearly 20 years.  They have 2 children, Aria and Micah, who have both surpassed their mother in height!

Pastor Drew received his B.A. in Intercultural Communication at California State University-Sacramento, CA.  A few years later he began his Seminary work and graduated from Golden Gate Baptist Theological Seminary (located in one of the most beautiful places in the world!) with a Masters of Divinity.  He had begun serving as a volunteer worship leader in 2000 when his father started a new church and needed a worship leader.  That opportunity greatly influenced Pastor Drew and gave him much valuable experience. 

After 10 years of service to First Family Church God moved Drew to another place of ministry…Cornerstone Baptist Church.  He and his family arrived here in Eldridge, Iowa on February 2nd, 2011, the day after the largest single snow storm in Iowa history.

Drew’s hobbies are hiking, music, cycling, and CrossFit.  Cycling is the form of exercise he enjoys most as it gets him in the outdoors and provides opportunities to commune with God out in His creation.  However, it is CrossFit that gets the bulk of Drew’s workout time these days and helps him stay active.

Drew’s passion is to help people experience God.  This happens in the music that is played and sung on the platform of Cornerstone, as well as in the preaching of sermons or teaching classes.  Helping people know God and worship Him with all that they are is of the utmost importance to Pastor Drew and is at the heart of his ministry philosophy.

Associate pastor

Steffan Nass

Steffan has taken a very non-traditional route in becoming Cornerstone’s Associate Pastor. After earning his B.S. in Mathematics from Iowa State University in 1986, he moved to South Florida and began working as a high school math teacher and football coach. It was during this time that he met, and immediately fell in love with, his wife-to-be, Sandy. They married in 1990.

In 1996 Steffan left teaching and began serving as a Special Agent with the FBI. Originally stationed in Miami, he later was transferred to the Springfield Division. Although his work took him across the country, and around the globe, his most memorable moment in the FBI was when he was introduced to, and immediately fell in love with, the person of Jesus Christ.

Steffan retired from the FBI in 2016 and joined the staff at Cornerstone immediately thereafter.

Steffan earned his M.A. in Ministry from Wesleyan Seminary at Indiana Wesleyan University.  

Steffan and Sandy have five children – Caitlyn, an Iowa State grad who is currently living and working in Virginia.  Abby works with the Pamoja House in Portland, OR. Connor recently completed his service with the USMC and is now attending UNLV. Kizza David just graduated from high school and will enter the USMC this summer. Kaggwa Francis passed away in 2017.

Dewitt Campus Worship Leader

Jacob Hayward

Jacob and his wife Caitlin moved into the DeWitt community in 2014, found Cornerstone – DeWitt, and soon made it their church family. Since then, they’ve added three joy-filled kids to their own family, Miles, Merrick, and Gemma.

Jacob started to see how God was molding him for serving the church when he saw how his enjoyment of singing and playing instruments could help fulfill a need for music for the high school youth group in which he was attending. After establishing and encouraging worship through music in the youth group, he was then offered opportunities to lead the entire congregation in music. Jacob then was given the opportunity to gather a diverse background in music styles and heart for leading people into worship through song after spending time in a variety of churches throughout his undergraduate and post-graduate schooling. He has had the joy of serving underneath the role of campus worship leader for Cornerstone since 2015.

“It’s humbling to know my role is not merely to lead people through a set of songs, but to use music to point a group of people coming from all different situations of life to the person and work of Jesus. It’s a joy and my prayer to help people see Jesus more clearly and engage with Him more intimately.”

Director of Children's ministries

Sandy Nass

Sandy grew up in Iowa and graduated from the University of Iowa where she had freshman rhetoric with a fun-loving girl named Heidi. After a spring break trip to Ft. Lauderdale, FL to visit Heidi’s brother Steffan, Sandy and Steffan fell madly in love, got married and settled in the Ft. Lauderdale area. After fourteen years of Florida sun, three kids (Caitlyn, Abby, and Connor), and an introduction to Jesus Christ, God brought Sandy and Steffan back to Iowa and to Cornerstone.

Sandy became Cornerstone’s Director of Children’s Ministries in 2012, and her passion is ‘…to tell the coming generation the glorious deeds of the LORD…’ (Psalm 78:4).

Sandy and Steffan adopted brothers David and Francis in 2013, completing their family. In 2016, Steffan took the not-so-traditional route of becoming Cornerstone’s Associate Pastor after a twenty year career with the FBI.

Sandy loves to spend time with her family.   Her daughter Caitlyn lives in Virginia Beach and is pursuing a career as a Registered Dietician. Daughter Abby teaches English to immigrants in Portland, OR.  Son Connor just completed four years of service in the United States Marine Corp and will pursue his degree at the University of Nevada, Las Vegas, this fall.  Son David just graduated from high school and hopes to follow in his brother’s footsteps by joining the USMC.
