But not all the "behind the scenes" people have been on the sidelines. An old adage states that: "Behind every great man stands a great woman". This is especially true of the Costellos: Mary and Jim. Mary has played an extremely vital role in the success of the Caballeros right from the beginning. It would have literally been impossible for Jim to have devoted the time and effort that he has to an organization such as the Caballeros without the encouragement, understanding and support of his good wife.
