What Cornerstone Communications does
Cornerstone Communications, LTD is a boutique strategic public relations and marketing communications agency founded in 1995 by Brooke Greenwald, a former journalist with experience at multiple Tier 1 media outlets. The firm is headquartered in Rockville, Maryland, and operates with a deliberately small team of 1-10 senior-level professionals, explicitly avoiding junior account executives. Its go-to-market is sales-led, driven by direct client engagement, consultation, referrals, and thought-leadership content rather than mass distribution.
