Our Origins

James Bell founded JBA in 1979 after working as part of a team at a Washington, DC, think tank developing new approaches to planning and conducting evaluations. Driven by a desire to help the health and human services sector accomplish what it set out to do, he recruited a team of professionals with a shared passion. Today, JBA is a nationally recognized, data-driven firm whose work helps organizations and the people they serve thrive.
