The museum offers long-term and changing exhibits, a speakers bureau, online resources for research, teacher training, school and public programming, summer camps, and special events. Each year, the museum serves 35,000 visitors onsite and nearly 100,000 people via its online resource materials available at www.JoCoHistory.org.

The museum is guided by two boards: one appointed by the Johnson County Commission and the second overseeing the not-for-profit Friends of the Museum organization. A staff of seven full-time and four part-time employees, with the help of over 60 community volunteers, oversees day-to-day museum operations.
