Making cities better

By seamlessly connecting volunteers with meaningful service opportunities, we are committed to transforming cities into vibrant centers of compassion and collaboration. Our mission is to cultivate a network where collective efforts lead to substantial and lasting improvements in city life.

Matching volunteers with local needs

Drawing from these insights and questions, Kaleo was conceived - an app and platform dedicated to connecting church volunteers and others eager to help with local needs, bridging gaps, and rebuilding essential human connections that foster strong communities.

An opportunity to simplify the path to serve

So we started to wonder if there was an easier way for volunteers to:

Connect with each other and answer the call to serve

Build an environment of growth, support, and compassion in their community

Bring grace, hope, and joy into other’s lives

Attract volunteers with the skills and availability they need

Kaleo simplifies the way volunteers connect, serve, and inspire. Our platform makes it easier to build environments of growth and compassion, attract skilled volunteers, and infuse grace, hope, and joy into community life.
