Here to Support Your Ministry
Serve Source exists to strengthen relationships and foster collaboration. Whatever stage your outreach or disaster response ministry is in, we're here to help you build it.
Host a Regional Roundtable
We're expanding opportunities for churches and partner organizations to host a DRRN One Day Roundtable, bringing Serve Source and trusted, ministry-focused disaster response leaders directly to your area. This one-day gathering connects church leaders, nonprofit partners, and disaster response ministries to build practical pathways for working together before, during, and after crises — so every leader leaves equipped to serve their community and become part of the response.
