Our kind of people

We attract passionate, motivated individuals who understand that no matter how committed we are, we are not the owners of the problems we seek to solve. We know that our commitment will never outlast those within the systems that are seeking to change it. Rather, we succeed by listening and supporting others. We are curious, creative, pragmatic and kind. Sound like you?
