Keith’s ministry among us has been extraordinary.

For 31 years, Keith Koster has shared his extraordinary gifts with Saguaro Christian Church. Across more than three decades, he has helped shape the worship life of this congregation in countless ways. Thirty-one is more than a number. It's thousands of Sundays, rehearsals, choir practices, Christmas Eves, Maundy Thursdays, Good Fridays, funerals, weddings, Easter mornings, celebrations and difficult seasons. It is choosing music for a particular moment, sitting down at the piano or organ, gathering musicians together, and helping a congregation find its voice. It’s living out one's faith in community with others. It’s leading Shelter and Bells and Choir and always remembering who needed a little extra attention. It’s the kindness shared when someone needed a reminder of belovedness. It's ALL of this and SOOOOOO much more. Keith has accompanied us, led us, challenged us creatively, helped us try new things, and provided a steady presence through season after season of Saguaro’s life. Keith’s ministry among us has been extraordinary. His creativity, musicianship, flexibility, faithfulness, and deep love he has for this congregation have left a mark on all of us that will last forever.
