He and his wife, Jackie, took their four kids and the trip truly changed the trajectory of his family’s life journey.

In his spare time, he loves to learn to do new things, build things, and to drive around town in his double-decker bus. If you see one at a BSU tailgate event, it’ll most likely be Randy and Jackie.

I love seeing how people’s lives in team members, my family, my church, and in Kenya are being impacted by this ministry.”
“I have loved being a member of the board and watching God guide and then provide in only ways He can do! God has taught me to trust His faithfulness even when things seem impossible.”

COLLEEN ZIMMERMAN, MD
Board Member, USA
Colleen, a family physician, learned about E.I. in 2010 through doctors Marietta Thompson and David Gee. “When they spoke of the work God was doing in Kenya, I knew I wanted to go and see myself. What I found was that the ministry of E.I. is completely Spirit-led and is transforming lives both in Kenya and in the United States. The partnerships that have formed are amazing – bringing together the gifts of God’s family from around the world to meet the needs of others.”
Colleen joined the board in the fall of 2017. Since then, she has become an integral part. Colleen and her husband, Chris, live and work in Spokane where they enjoy their son and the great outdoors.
Board Member, USA
In 2011, Rob, a Battalion Chief with the Eagle Fire Department and lobbyist for the Professional Firefighters of Idaho, met a physician that had gone with E.I. on a trip who shared her experience with him. Rob’s interest was ignited. “I’d wanted to go on a mission trip and this seemed like a fantastic opportunity. The call that God put on my heart to choose Kenya was nothing more than a strong desire inside – so I went.”
Knowing Rob’s passion for the eternal impact of the work of E.I., the board asked him to join at the end of 2018. We are excited for all he brings to the table. Rob has been married for 18 years and has four lovely daughters. Rob also enjoys fishing and is passionate about working with fire departments on union issues like firefighter’s health and safety.
