The Greencreek Community Hall has an elected board that serves to oversee the operations and maintenance of the facility.

There is a Catholic church in Greencreek known as Saint Anthony's Parish.

As part of the parish there is still an active group called the "Saint Anthony's Society" that serves as a governing board for the church as well as providing community service projects, most notably the Greencreek Fourth of July celebration.

Greencreek's primary industry is agriculture; however other small businesses do exist in the area.
