The McKendree Metro Rec Plex in O'Fallon was completed in early 2017 and is one of the premier recreation facilities in the Metro East region. The focal points of the facility are Poettker Arena and the Aquatic Center.
Poettker Arena is home of the McKendree University Men's and Women's hockey teams, as well as, the youth club Southern Illinois Ice Hawks. The arena boasts 2 NHL-sized hockey rinks with sizable viewing areas and capacity to seat large crowds. One of the rinks can serve as a convertible multipurpose area to host concerts and other special events.

Inside the center is a heated, 10-lane Championship Competition pool with (2) 1-meter diving boards, (2) 3-meter diving boards and (1) 5-meter diving platform. The McKendree Metro Rec Plex is membership based, but also availble to non-members through the purchase of all-access day passes.
