Our Mission
We live to give everyone the chance at a fresh start with Jesus and His Church — providing people of all ages, races, and walks of life an opportunity to pursue their full potential.
Our Story
Overflow Church began with a simple but powerful vision: create a place where people (especially college students) could encounter God in a real and meaningful way. In its earliest days, that vision took shape through a college ministry called the Jesus Movement, which served students attending nearby universities. It wasn’t tied to a single church or background; instead, it brought together students from many different places to experience passionate worship and biblical teaching from leaders across the region. What started with a small group of about a dozen leaders quickly gained momentum, as more and more students began showing up, hungry for something authentic. Before long, the ministry outgrew expectations, even establishing its own space downtown as the energy and impact continued to grow.
As the Jesus Movement expanded, something unexpected began to happen, people beyond the college crowd wanted in. Adults from all walks of life started asking if they could attend, be part of the gatherings, and experience what God was doing. It became clear that this wasn’t just a college ministry anymore; it was the beginning of something bigger. After much prayer and conversation, those original leaders sensed it was time to take a step of faith and plant a church. In 2015, Overflow Church officially launched. From the very beginning, God moved in extraordinary ways. Within just a couple of years, the church grew from a handful of people to hundreds gathering each weekend, filling multiple services in a small downtown building.
Like any real story of faith, the journey hasn’t been without challenges. There were seasons that required perseverance, trust, and a renewed sense of direction. In late 2018, Pastors Alex and Samantha Gallien stepped into that story, and in 2019 Pastor Alex officially came on staff as Lead Pastor. Since then, Overflow has continued to grow and take new ground, moving into its current home on Highland Drive in early 2020.
Today, we’ve seen countless lives changed, people encountering God, marriages restored, students discovering purpose, and hundreds baptized. Overflow Church is more than a place; it’s a community being shaped by God’s presence and committed to helping people know Him and follow Him. And as we look ahead, we truly believe the best is still to come.

Our Foundation
All our teaching and ministry is rooted in and flows from these biblical truths, in line with the historic faith summarized in the and .
The Bible is God's Word to all people. Written by human authors under the supernatural guidance of the Holy Spirit, it is truth without any mixture of error and completely relevant to our daily lives.
God is great, all powerful, all knowing, ever present, and completely worthy of our trust. He is our Father: loving, compassionate, and faithful to His people and His promises.
Jesus Christ is the Son of God, co-equal with the Father. He lived a sinless life, offered Himself as the perfect sacrifice, rose from the dead after three days, and will return to reign as King of Kings and Lord of Lords.
The Holy Spirit guides believers into all truth, convicts of sin, comforts us, gives spiritual gifts, and makes us more like Christ. His presence assures us of our relationship with Jesus.
God has existed in relationship with Himself for all eternity, one substance in three persons: Father, Son, and Holy Spirit. Though each serves different functions, they each possess equal power and authority.
The Church is a local community of believers unified through faith in Christ, committed to His teachings, His commands, and bringing the Gospel to the world in love and unity.
The blood of Jesus provides the only way of salvation through forgiveness of sin. Salvation occurs when people place their faith in the death and resurrection of Christ, it's a gift from God, not earned by our own efforts.
We practice baptism by immersion the way Jesus was baptized, symbolizing the death and resurrection He went through for us. It is a public declaration of our new life in Christ.
Colossians 2:12
Water BaptismPeople are made in the spiritual image of God. Although every person has tremendous potential for good, all of us are marred by sin, an attitude of disobedience toward God that separates us from Him.
Prayer is the ability to communicate directly with God. Through Jesus' salvation, we no longer need an intercessor, we can address the Father personally and directly.
People were created to exist forever, either eternally separated from God by sin (Hell) or eternally with God through forgiveness and salvation (Heaven). Both are real places of eternal existence.
