Optimist Clubs are dedicated to "Bringing Out the Best in Kids" and do their part through community service programs. Optimists internationally conduct 65,000 community service projects each year, spending $78 million in their communities. Annually, six million kids are positively affected by Optimist programs.

For over forty years, the McCook Optimist Club has been serving the youth of McCook, Nebraska and the surrounding communities through support in academics, athletics, and performances.
