About Us

Chapel of the Lake is a non-denominational church unified around the belief that the Word of God should shape and guide every facet of our lives. 

 As we grow together, we hope to build relationships and make lasting impact in our community by sharing God's love which is open to all who seek Him. 

Values and Culture

We are a community of people who have joined together to pursue Christ, proclaim Christ, and practice His love.

The Chapel has determined four essential engagements that drive everything we do: Grow, Connect, Serve, Reach. 

Grow is focused on growing people in their faith and knowledge of God. Growth happens in a variety of ways, and we encourage everyone to be pursuing at least one area of spiritual growth. A few ministries that are focused on growth include sunday school classes and mid-week bible studies. 

Connect is focused on connecting people to the church and its family. No one is expected to live life by themselves, and the church offers real community based on God and His word. Connection begins with the worship service and is hopefully continued throughout the week through fellowship events and home groups.

Serve is focused on using our gifts and abilities to serve God and others though the various ministries of our church. Service happens in response to spiritual growth and in connection with the church body. Whether it's service inside our church, or out in the community, every Chapel member is encouraged to get involved!

Reach is focused on reaching out beyond the church walls and into our community and the world. It is the duty of all Christians to be a light for the gospel in their sphere of influence. By supporting various community organizations, ministries, and global missionaries we hope to bring the hope of Jesus to a world in need.

New Here?

If it's your first time at the Chapel, welcome! We know every church is unique, so here are a few frequently asked questions to help you plan your visit. 

The 8:30am and 11:00am services are identical, but nursery and children's church is only available during the second service at 11:00am. Sunday School for all ages begins at 10:00am.


Where do I go when I get there?

When you pull in the parking lot, you'll find guest parking right up front. As you enter the building, our team of greeters will meet you and show you where to find the sanctuary, restrooms, and children's ministry areas. If you need anything during your visit, please don't hesitate to ask!

What do you do for kids?

We encourage families to stay together for the first portion of our worship service, but there is also a children's church available for all children 5th grade which is dismissed before the sermon starts. Children's nurseries from birth-3yrs are available throughout the entire second service. Check out our Children's Ministry page here.

What should I wear?

Don't feel like you have to dress up. You'll find a wide range of dress (from jeans & t-shirts to a few coats & ties), so you are welcome to wear whatever makes you comfortable.

We would love to get to know you better, and have a digital connect card that will help us answer any questions you might have.
