WASHINGTON — Firehouse Strategies has acquired Scarlet Oak Strategies, expanding the public affairs firm’s expertise in grassroots and grasstops campaigns.

The deal gives Firehouse access to Scarlet Oak’s network of more than 1,200 political operatives across the country.

Scarlet Oak founder Raymond Glendening, a former Democratic Governors Association political director, will join Firehouse as a partner. Brian Doory, currently a Scarlet Oak managing director, will join Firehouse as an MD.

“We’ve had the pleasure to partner with Scarlet Oak on several projects, and their ability to build constituencies and execute grasstops and grassroots campaigns is second to none,” Firehouse said in announcing the deal. “And we're not the only ones impressed: Their client roster includes some of the biggest brands and biggest public affairs campaigns in the country.”

The acquisition comes roughly six years after Terry Sullivan and Alex Conant, both longtime political strategists, started Firehouse after managing US Sen. Marco Rubio’s 2016 presidential campaign.
