A colleague of mine had me briefed on another Sacco. 'Ukiristo na Ufanisi' administered by Emmanuel church in Kawangware. It serves all sorts of people' christians and non christians alike.All you need to join is to form a cell of 5 people and you go to them for registration.you may need an introduction from a member.
My colleague has been in the sacco for 6 years and it has served him well.
Membership is open to all n sundry,so you get Mama Mboga in the same interaction with Accountants,Land lords,engineers,Business executives and Jua kali's all blended together.
Registered with cooperatives and run by professional church volunteers.
