Brian loves all things outdoors, family, sports, history, politics, and preaching the scriptures! He enjoys a good cup of coffee or a pint along with a great conversation.

"I have given God every reason known to mankind to walk away from me. Every morning I open my eyes and find he is still there with love and forgiveness!" - Brian

Tanner Kaler - Worship/Technology Assistant

Tanner Kaler is a Colorado native and joined the Rock Creek Church staff in January 2021. An avid reader and musician who loves teaching and learning about everything, he married his beloved Amy in May and is enjoying life as a newlywed.

Ethan Arnett - Worship Intern

Ethan Arnett recently returned to Colorado after spending a year at Montana Bible College, where his knowledge and passion for God grew immensely. He loves all things outdoors and cars.


Rock Creek Church is an Elder led church. Elders are nominated and elected by the congregation to oversee the ministries and operations of the church. The pastoral staff submits to the Elder Board and are responsible for the day-to-day life of the church. The Lead Team is comprised of volunteers who are responsible for specific ministries.
