Kellie and Kristen are twin sisters united by one mission: to see the glory of God exalted and enjoyed among people from every nation. Based in Nashville, Tennessee, they live, work, write, and serve faithfully within their local church community. Music has been woven into their story from an early age. Kellie began singing at just three years old, while Kristen picked up her first instrument at the age of eight. For more than two decades, the sisters have ministered through music, each sensing God's call on their lives as teenagers.

Over the years, Kellie and Kristen have collaborated with respected Christian artists and songwriters including Cody Carnes, David Leonard, Meredith Andrews, Jacob Sooter, Jess Cates, Tony Wood, Krissy Nordhoff, and many others. Together, they have released three albums and continue to write songs and lead worship around the world. Most recently, they led worship at a Bible conference in Istanbul, Turkey.

"The Bible tells us that two things will last forever: the blood of the Lamb and the word of our testimony. Because of His blood, we have a testimony," says Kellie. "That's why we sing and write about the truths that will endure for eternity. Our hope in worship is always that there would be less of us and more of Him." She continues, "We will proclaim this until the whole world knows that He is the greater Adam, the perfect Priest, the spotless Lamb, the pursuing Shepherd, the loving Father, and the mighty King."
