Headquartered in Washington, D.C., Cornerstone has an established federal, state and local presence.

The firm’s state and local footprint stretches across the Northeast to the Mid-Atlantic, South, Mid-West and Mountain West. We have office locations in 11 states, housing more than 45 professionals.

In addition to our physical office locations, Cornerstone actively represents clients in Delaware, the District of Columbia, Massachusetts, and Montana. We also maintain relationships with select consultants in states where we do not have a physical presence.

Our firm works closely with national organizations such as the Republican Governors Association (RGA) and the Democratic Governors Association (DGA), the Republican Attorneys General Association (RAGA) and the Democratic Attorneys General Association (DAGA), giving us insight into statehouses across the country.
