OUR MISSION

To live the uncommon, surrendered life that reflects Jesus.

We believe that when ordinary people fully surrender to Him, He transforms how we live, love, and give—shaping lives marked by grace, generosity, hope, and God’s presence.

The Uncommon Life is the natural overflow of a transformed heart. It shows up in how we treat our families, love our neighbors, and serve our world—allowing the light of Jesus to shine through everything we do.

Romans 12:1–2; Matthew 5:14–16

OUR LEADERSHIP

PASTOR GUILLERMO

Pastor G is the Lead Pastor of NorthRock Church, a thriving, multicultural, and biblically-rooted church in Aubrey, TX. Born in Cuba, he moved to the U.S. at six, shaping his deep faith, perseverance, and love for people. He and his wife, Julie, have been married for 20 years and have three daughters.

Before stepping into full-time ministry, Pastor G built a diverse background in leadership, media, and team development, equipping him to connect with people and inspire transformation. His experience spans roles in executive media, campus pastoring, and ministry leadership, shaping his ability to reach people where they are and help them grow in faith. As an endurance athlete, he applies discipline and perseverance to both faith and leadership. His engaging, Scripture-rooted preaching is centered on seeing lives transformed by the power of Jesus.

“We are called to an uncommon, surrendered life that reflects Jesus—and that changes everything.”
