The word Sachem, or chief, is borrowed from the language of the Algonquian people, who were the original inhabitants of New England. In Algonquian communities, the Sachem was a leader who, through his actions, earned the trust and respect of those he served. Sachem was chosen as our firm’s name to evoke its New England roots while also affirming its guiding values.

In all affairs, Sachem Strategies places the highest premium on the values of trust, respect, and a commitment to excellence. Guided by these principles, we have built strong relationships among federal policymakers and have earned a loyal network of clients.
