Welcome to the Oskaloosa Indoor Sports Complex website.  

The OISC is a volunteer run, 501 (c)(3) non-profit organization dedicated to providing indoor practice opportunities for young athletes in Mahaska County. It will be generously available to all members because we believe "Champions are the Last Ones to Leave!"  

This 13,000 square foot facility was gifted to the OISC by Clow Valve to provide a multi-sport training facility for the Oskaloosa Community and surrounding areas.  We aim to serve the many young athletes in Oskaloosa as well as adults that wish to stay active and improve their game!  The facility is equipped with full surface area turf, two 70' batting cages, baseball and softball equipment, golf inserts and mats, keyless entry and security system in place.  The Phantom Batting Cages are fully removable, and will provide athletes and teams usage of the wide open turfed area.    

As a non-profit, facility improvements will depend on fundraising efforts, donations and membership.
