Diversified Communications is a third-generation, family-owned business-events and digital-media company founded in 1949 by former Maine Governor Horace Hildreth. It developed from a single Portland, Maine, radio station into an international organization serving professional communities through exhibitions, conferences, educational programs, networking, digital publications, and industry-focused media platforms.
The company’s portfolio spans sectors including seafood and food processing, maritime and commercial fishing, active lifestyle and outdoor retail, healthcare, technology, geospatial and built-world applications, aviation and drones, natural products, and workplace and design. Diversified’s event model is built around connecting buyers, suppliers, producers, and service providers while adding year-round value through content, communities, professional education, and digital channels.
Its shows range from large international marketplaces to specialized conferences and regional or national business events. Notable properties include the International WorkBoat Show, Seafood Expo North America, Seafood Processing North America, The Running Event, Commercial UAV Expo, Geo Week, Natural Products Expo East, and Pri-Med conferences.
The organizer operates from the United States and maintains international operations serving markets in Australia, the United Kingdom and Europe, Hong Kong, Canada, and other locations. Its global portfolio is designed to support industries that influence the wider economy, while its specialist brands provide targeted access to qualified professional audiences.
Diversified’s value proposition for exhibitors is a combination of face-to-face business development, industry-specific buyer access, educational programming, networking, and supporting digital media. For visitors, its events offer product discovery, market intelligence, training, and opportunities to build commercial relationships.
The company moved its U.S. and global headquarters to Two Portland Square in Portland’s Old Port in 2026.
