Rev. Dr. Rebecca Tuimising
Wife to Bishop William K. Tuimising, mother of five, and a steady partner in ministry for more than fifty years.
Mama Rebecca
Behind six decades of ministry stands a partnership few get to see up close. Rev. Dr. Rebecca Tuimising has walked alongside Bishop William K. Tuimising since the earliest years of his calling — through the founding of churches, the raising of a family, and the quiet, steady work of building a legacy that outlasts a single lifetime.
To many across the church community she is known simply, warmly, as Mama Rebecca — a name that carries decades of pastoral care, hospitality, and quiet strength.
A Golden Jubilee of Marriage
In 2023, Bishop William and Rev. Rebecca Tuimising marked the Golden Jubilee of their marriage with a renewal of vows at Deliverance Church along Langata Road, Nairobi — a celebration attended by fellow church leaders and dignitaries, including Pastor Dorcas Rigathi, wife of the Deputy President.
Fifty years on, their marriage still stands as a living example of the same message Bishop Tuimising has preached for a lifetime — that what matters most is not how you start, but how you finish.
A Mother to Five, Grandmother to Many
Together with Bishop Tuimising, Rebecca has raised five children and welcomed many grandchildren into a home built on the same faith, consistency, and hospitality she has extended to the wider church family for decades.

MAMA REBECCAA Trustee of Finishing Well Foundation
Rev. Dr. Rebecca Tuimising serves as a Trustee of Finishing Well Foundation, lending decades of pastoral experience and quiet governance to a mission she has lived out long before it had a name. Her presence at the Foundation's gatherings — from formal galas to community appreciation events — reflects the same hospitality and steadiness that has marked her life in ministry.

Appreciating Those Who Serve
At Finishing Well Foundation's community appreciation events, Rebecca is often found honoring others rather than being honored herself — presenting gifts of gratitude to the mothers, fathers, and volunteers who carry the mission forward on the ground.
A Quiet, Constant Presence
Whether standing beside Bishop Tuimising at national and ministry engagements, or seated quietly in the background of a service she helped make possible, Rebecca's ministry has rarely sought the spotlight. It has instead shown up, again and again, in the steady work of showing up — for her husband, her children, her church, and now, for Finishing Well Foundation.
Thank You, Mama Rebecca
For fifty years of partnership, a lifetime of quiet service, and a family and foundation still standing because of the steadiness you brought to it — thank you.
