His life was defined by determination, devotion to family, and a lifelong commitment to serving others. Whether at home, in his community, or throughout his distinguished career in public safety, Billy lived with purpose, conviction, and compassion.
An avid outdoorsman, Billy had a lifelong passion for fishing, enjoying the waters of Louisiana, Texas, Florida, and Panama. A licensed fishing captain, he was a founding member of the New Orleans Big Game Fishing Club and a lifetime member of the Southern Yacht Club.
Billy dedicated more than four decades to public safety, serving as a firefighter, Fire Chief, and Emergency Management Director, including 25 years leading emergency management for Monroe County, Florida, encompassing the Florida Keys and mainland Monroe County. He earned national recognition as a pioneer in hurricane preparedness, emergency management, and disaster response.
Among his many contributions, Billy helped develop one of the nation’s earliest regional hurricane evacuation studies and plans, laying the groundwork for modern evacuation planning. As the first local emergency manager to serve on FEMA’s Hurricane Liaison Team, he strengthened coordination between the National Hurricane Center and emergency management agencies nationwide.
A tireless advocate for public safety, Billy testified before Congress and played a key role in preserving critical National Weather Service operations in Florida. His distinguished service earned numerous honors, including the prestigious Neil Frank Award, FEMA Director’s Award, Emergency Management Director of the Year, and other state and national recognitions.
