Vianney Largillier

US Flood Barrier was born out of lived experience, deep roots, and a clear purpose: to protect our home, our neighborhood, and the places we love.
Vianney has always lived within 2 miles from the sea, from coastal France to now Naples, Florida. With a background in construction and heavy equipment, he has a keen understanding of how vulnerable our infrastructure is—and how devastating and expensive storm damage can be. He’s seen first-hand the years-long rebuilding it can take after a major storm, and the emotional cost it takes on families and small businesses.
Together with Omer, they created US Flood Barrier to protect their community, state, and country from rising waters. They have worked on many projects together and independently across Southwest Florida. Vianney lives in Naples and focuses on the area from Marco Island to Estero. Omer, who lives in Fort Myers, focuses on the area from Estero to Punta Gorda. As a team, they offer local expertise and responsive, tailored solutions.
This isn’t just a business. It’s a calling.

US Flood Barrier. Calm in the storm. Protection you can trust.
