ADRN Leadership

Daniel Geraci
Executive Director and ADRN Founder

A lifelong Austinite, Daniel Geraci founded the Austin Disaster Relief Network in March 2009. Under his leadership, ADRN has grown to a network of more than 170+ churches and supported more than 18,000 survivors, trained more than 5,000 volunteers and donated more than $4.5 million to rebuilding and recovery.
ADRN’s support spans five counties surrounding Austin, Texas. ADRN network churches together deployed volunteers to five significant disasters, such as the Memorial Day Weekend floods of 2015 and the October 2015 floods, which each impacted more than 1,800 families.
Inspired by his personal volunteer experience sponsoring two surviving families from Hurricane Katrina in 2005, and evacuees of subsequent disasters, Daniel envisioned a network of Austin churches who would set aside theological differences and mobilize together to embrace people in times of need. To develop ADRN, Daniel built on his career in sales and entrepreneurship and his experience organizing city-wide religious programming, such as the House of Unity ministry, which reached individuals in high-crime areas, and the Celebrate 2000 prayer service ushering in the new millennium.
Daniel lives in Cedar Park, Texas, with his wife and two daughters. He serves on the worship team at Church of the Hills, where he plays the bass guitar.
