At FCB Chicago, the Account Supervisor is the liaison between the agency and the client, the bridge between the brand and creative strategy, the communicator between all the internal teams, the mentor for junior members of the team, the champion and challenger of good ideas. This person knows how to build relationships—not just with the clients but internally as well. This person understands a client’s business—what levers drive the machine—and finds the best place for the agency in that model.
