Mattio Communications is a New York-based communications agency specializing in the cannabis, CPG, and emerging-industries sectors. The firm was founded in 2005 by Rosie Mattio and has built one of the most established cannabis practices in U.S. public relations.
Client work has included Canndescent, Navy Capital, Seed & Smith, Flowhub, Papa & Barkley, and botanical SEATTLE, alongside operators, ancillary businesses, and cannabis-adjacent CPG brands.
Executive visibility, story development, press release drafting, media placement in trade and consumer press, and crisis communications. The media relations practice is the firm's core discipline, with a specialization in the regulatory and reputational sensitivity that cannabis coverage requires.
Technical site audits, keyword strategy, and localized cannabis SEO in states where medicinal and adult-use programs are active. Tracking through Google Search Console and Google Analytics, keyword targeting by relevance and volume, and adjustment for algorithm changes.
IR programs designed for cannabis operators navigating public and private capital markets. The firm builds narratives for target financial audiences, coordinates disclosures, and manages relationships with securities analysts, investment bankers, and the financial press.
Cannabis PR is a specialization — federal Schedule I status restricts advertising channels, media coverage carries regulatory sensitivity, and IR requires understanding the disclosure environment for a category that trades on Canadian exchanges more than U.S. ones. Firms with generalist practices frequently subcontract cannabis work to specialists. Mattio has built the practice in-house since 2005.
