The Apex Gallery was established in 1989 and is housed in the Classroom Building. It offers educational Arts and Science exhibitions for the enjoyment and enrichment of people of all ages.

The gallery features contemporary works of artists and scientists, many of whom are nationally and internationally recognized. These exhibits are designed to reflect a cross section of cultural expressions and perspectives.

In addition to providing on-campus students and staff with opportunities to view the exhibits, the Apex Gallery offers tours to local middle-schools, features lectures from visiting artists, provides campus and community workshops and conducts collaborative programming and exhibitions with Rapid City's Dahl Fine-Arts Center.
