The GMCC is responsible for long-range and capital planning, executive staffing, human resources, financial office and accounting, computer technology, and major fundraising for the five units under the GMCC corporate umbrella. By centralizing these business functions and services, each center's director is freed to concentrate on programming, membership, and customer service. Additionally, each center is able to share personnel with the other centers, and request staffing assistance from the other centers for special events.Two unused classrooms at the Midland Community Center (MCC) received a makeover to become the offices for GMCC personnel in 2007.
