In 2012, Marty Harris and Don Mader formed a strategic partnership to expand Southeastern’s range of services by forming SEP Communications to offer promotional products as a new solution for clients. By combining Marty and Don’s expertise in business, print, and marketing, they successfully broadened the company’s capabilities—making it easier for clients to source both high-quality print materials and branded promotional items through a single, trusted partner.
Fast forward 13 years, and we’re proud to share that SEP Communications LLC ranked #27 on the Fastest-Growing Companies – Under $25 Million list in the August 22, 2025 issue of the South Florida Business Journal!
SEP Communications delivers exceptional promotional products and branded merchandise solutions that help our clients shine. This recognition reflects Marty and Don’s vision and leadership — backed by the drive, creativity, and dedication of the amazing Southeastern and SEP Communications teams. Please join us in celebrating this well-deserved honor!
