Triou Marketing

Triou Marketing, LLC is a woman-owned corporate events and marketing company based in Lancaster, Pennsylvania that also operates an out-of-home advertising division branded Triou Outdoor. The company offers three main service areas: corporate event planning, marketing consulting, and out-of-home advertising, providing a customized, concierge-style client experience across each. Within its OOH practice, Triou provides billboard placements and high-profile out-of-home inventory, with markets that include Harrisburg, Las Vegas and Upstate New York, positioning itself to help brands secure billboard and outdoor advertising space in these areas.

The firm markets itself as bold and innovation-driven, partnering with clients through research and immersion to develop tailored advertising and event strategies. Its stated client work references brands such as Sight & Sound, Stark Law LLC, LIFT Incorporated, Duck Donuts and Christie Engineering. As a small team, Triou functions primarily as an agency and buyer/broker that arranges out-of-home placements on behalf of clients rather than as a large media owner of proprietary billboard structures, combining OOH media buying with broader marketing consulting and corporate event services.

Advertisers engage Triou to plan and place billboard and outdoor campaigns alongside integrated marketing and event support across its regional footprint.
