Nick Dedetsinas

Lead Pastor

I was born and raised in Joliet and because I grew up in a Greek home, my life consisted of soccer, good food, and family. I am married to my wife, Kaly and we have three kids with a whole lot of personality. I love serving at Grace because every day I get a front row seat to see Jesus in action. My prayer is to see the congregation grow in a deeper and wider love for the gospel.

Peter Vienne

Family Pastor

I was born in Joliet and I grew up in Morris, IL. I am a servant of the Lord Jesus Christ, husband of Cortney, and a father of four amazing children. I am so grateful to God to be serving at Grace Bible Church as a Pastor to families. God cares so deeply for whole families and it is one of the ways he relates to his people as a part of the household of God. My prayer is to see the gospel of Jesus Christ be embraced, treasured, and proclaimed through the families of Grace Bible Church.

Sean Speakman

Creative Arts Pastor

I grew up as a military kid, so I moved often,  but spent most of my time in the southeast. My wife, Sara, and have been married since 2019 and have the privilege and honor of raising our daughter Charlette. I am passionate about creating a theology of worship that focuses on the Gospel, and continually points believers to the finished work of Christ on the cross.

Katie Baier

Pastoral Assistant

Grace Bible Church has been our home for over a decade. I have a passion to connect people here at Grace, make them feel welcome and to make Jesus known in our lives and throughout our communities.  My husband Tim and I have 3 daughters: Kailey, Maddie, and Mack. I am someone who is grateful for everyday, finds humor whenever possible and spending time with my family is my all time favorite thing to do!

Sue Sperling

Finance Admin

I have lived in the Plainfield/Joliet area for about 16 years. I was born and raised a Green Bay Packer Fan (I am usually everyone's favorite Packer Fan)  I am married to a Bears fan, Patrick Sperling, and we have 3 kids: Matthew, Evva and Adalyne. Grace has been our Family Church for almost 10 years. I love serving at Grace, from decorating at Christmas, mowing grass, kids check in and all things finance. I love being with my Grace Family.

Kaly Dedetsinas

Women's Ministry Lead

I grew up in the south suburbs of Chicago and I’m a die hard Patriots fan. Some of my favorite pass times are a good board game or leisurely strolls through the aisles of Target. I’m married to my husband Nick and we have three beautiful tiny humans. I love serving in women’s ministry because I’m passionate about watching the truth of the gospel permeate and transform the lives of the women at Grace!

Tim Reilly

Men's Ministry Lead

Laura and I came to Grace 26 years ago, drawn here first by the great ministry to children and young adults. Over the years, we have been blessed by the example of older believers at Grace living out their faith. As an older man now, my goal for men’s ministry is to help the men of Grace share life together and grow in their relationships with Jesus just like what was modeled for me!
