Harmelin Media

Harmelin Media is one of the largest independent media services agencies in the United States, offering media planning, buying, and strategy across channels including a dedicated out-of-home practice. Founded in 1982 by Joanne Harmelin, it was among the region's first agencies devoted solely to media planning and buying, and it remains independently owned. The agency is headquartered in the Philadelphia area, in Bala Cynwyd, Pennsylvania, with additional offices supporting markets such as Chicago, Los Angeles, and Pittsburgh and staff spread across many states.

Harmelin describes its focus as full-funnel, data-driven performance media, helping clients navigate an increasingly complex and measurable media landscape across traditional and digital channels. Its out-of-home capability is a notable differentiator: rather than outsourcing OOH execution, Harmelin keeps out-of-home buying in house and uses specialized software to assess, map, and report on available units for maximum efficiency. Out-of-home campaigns are grounded in research into buyer behavior and market evaluation, with placements spanning digital and traditional billboards, transit, street furniture, buildings, schools, arenas, and a wide range of other signage options selected to reach defined target audiences.

As a buy-side partner, Harmelin serves a client roster that includes numerous Fortune 500 companies across many industries. For advertisers, Harmelin offers the scale and analytical rigor of a major independent agency combined with an integrated, self-executed out-of-home team that connects OOH to broader cross-channel media plans.
