[1] Leo clubs encourage youths to develop leadership qualities by participating in social service activities.

They conduct various projects in the fields of health care, elders, children, disabled people, literacy and education, and self-development.

The first Leo club was founded in 1957 by Jim Graver, the coach of the Abington High School, Pennsylvania baseball team.

There are no major differences in the operations or logistics of Alpha and Omega Leo Clubs.

They also have representation at all Constitutional Area levels with a body called, the Leo Advisory Panel which is a mirror of the International Board of Directors.
