One Firefly, LLC is an award-winning marketing agency that caters to technology professionals in the custom integration, security and solar energy markets. One Firefly is headquartered in Davie, Florida with staff located throughout North America and has been operating since 2007.


We come from a desire to help organizations find solutions to otherwise challenging problems. With a Mechanical Engineering degree from Virginia Tech under his hood and successful sales career tracks with two leading technology manufacturers, Lutron and Crestron, Ron Callis founded Firefly Design Group in 2007 with the aim of providing system design and documentation services to clients worldwide. Ron would quickly recognize the industry’s need for targeted marketing solutions and soon added a dynamic team of marketing professionals in part through a partnership with industry veteran and pioneering business leader, Federico Bausone. The result was an agile, solutions-driven team of professionals we call One Firefly.


We’re looking to consistently develop new services to help technology professionals adapt and succeed in today’s digital marketplace. Whether it’s our award-winning Mercury Collection websites or our innovative content marketing system, “CM2.0”, everything we do integrates the latest in marketing innovation, enabling us to provide solutions that adapt to our client’s constantly-changing business environments.
