Meet the Pastors

Marty Sloan

Lead Pastor
I am passionate about communicating the word of God and helping people of all ages and cultures to know God, find freedom, discover purpose and make a difference in this world. My desire is to know Christ and make Him known to others.

I became lead pastor of Calvary Church in January 2020. Former lead pastor, Randal Ross, retired in December of 2019, and after one visit to Calvary, I knew this would be my new home. A vote was held in November, and we made it official. I cannot wait to see what God holds for the future of Calvary, and I am humbled to be along for the journey.

I have been an ordained minister since 2000 and have served in ministry for over 25 years, including various staff roles, and as lead pastor since 2009. I love reading, weightlifting, traveling, hunting and football. My wife, Becky, and I have been married since 1994 and have two sons: Chandler and Landon.


I have had the honor of serving in ministry for over 20 years. I am passionate about making disciples of Jesus Christ who love God and love others. My incredible wife, Lynnelle, and I have three amazing kids: Abigail, Malachi and Liliana. Our family loves serving, laughing and sharing a meal with old and new friends.


Assimilation & Next Steps
"Love God, Love People" is my purpose. My passion is for people to experience the real Jesus and step into their full potential in Him. I have been married to my wife, Julie, for 21 years, and we have 3 children: Jessica, Jared and Joseph. We love watching movies and spending quality family fun time together.

Kids & Families
I knew in 8th grade that I was called to be a children’s pastor. Over time, God opened my eyes to the need to help young people understand His plan for their lives. Serving in full-time ministry since 2002, my wife, Kristi, and I love to see the best in young people as they grow. Our three children (Ava, Alia, and Gavin) help sharpen our skills for discipling students of all ages in their walk with the Lord.

 Music & Missions
I love directing church choirs and leading people in worship. Music is one of my great passions in life. I have been in music ministry for over 27 years, and my wife, Taunya, and I began serving at Calvary Church in 2007. Taunya and I have two children, and we are very proud of them.

Education & Discipleship
My life and ministry are founded in my first love, Jesus Christ. "He is my light, my strength, my song... my all in all." My first earthly passion is my amazing wife, Michelle. Our calling is to share the love of God in which we stand. For over 25 years we have worked together to help people of all ages see hope replace despair, love conquer division, and freedom break bondage through knowing and applying the truth of the Word of God.


Campus Development
I have been married to Ericka since 2010, and since then, we’ve been active in planting churches in Berkeley, California, and the Chicagoland area. I enjoy reading, writing and speaking. Ericka and I come alive when people immerse themselves in the mystery of Jesus.


I have grown up and served in many ministries at Calvary. I came on staff in 2014, and I love serving the church and surrounding community. My wife, Jesica, and I are passionate about expanding the kingdom of God by using the local church to bless those in need. We have two children (RJ and Naya), and we love staying active, being outside and finding new parks.

Jeremiah Miller

My deepest passion is to make more disciples of Jesus. My mission is to live a life of worship that communicates and unveils the heart of God. I’m dedicated to equipping the next generation to advance His kingdom. From a young age, God called me to ministry. Over the years, He continues to walk me through new ways to bring him Glory. I love playing music, songwriting, playing sports and getting to know new people.

I have been serving in junior high ministry since I was 17 years old, and I have a strong call to serve and encourage the next generation. I have been on staff at Calvary since 2014, and it is a great joy seeing young people encounter God and find hope in Him. I also have a secret love for interior decorating and lemon bundt cakes!


Calvary Español Lead Pastor
My passion for Calvary Español brought me to the role of its lead pastor. I love watching the congregation grow (and grow in faith) each week. My love for ministry is second to my love for my wife, Becky, whom I met while we were both serving in the military. We have been together for 22 years and have two children: Caleb and Dannielle.

Finance Director
I was born and raised in Denmark. I came to the states in 2002 and joined Calvary in 2004. Since coming to Naperville, I met my wife, Erin, who works in education, and we have two kids: William and Anna. We are passionate about the work of the local church and the crucial impact it can have locally and abroad through missions work.

Stewardship & Development
I love serving God by serving others. I joined Calvary Naperville in 1988 and served as the church administrator until 2016. My passion has always been to be a helpmate to those around me. The joy of my life is my wife of over 50 years, as well as our daughter and two grandchildren.

Wanda Burgund

My call to teach and encourage others first found fulfillment when teaching Sunday School to kindergarteners when I was 15. That same calling has directed me as a professional counselor, teacher, conference speaker and leader of mission teams to many countries. As an ordained minister of the Assemblies of God, it is a privilege for me to serve the congregation of Calvary Church.   


I have been married to Jeff since 2010, and we've planted churches in Berkeley, CA, and the Chicagoland area. It is an honor to be able to serve the Lord together in ministry. I am an ordained minister with the Assemblies of God and a doctoral candidate at the Assemblies of God Theological Seminary. I am passionate about helping others better understand God and His Word.

I serve as a pastor over Calvary’s web church, and I work with pastoral care. My wife, Michelle, and I were married in 2013, and we share a heart for connecting and ministering to those in need. We do everything we can to bring the message of Christ to them through the various ministries of Calvary Church. Michelle and I have two daughters.
