About Us

The Grossmont-Mt. Helix Improvement Association (GMIA) is a non-profit 501(c)(4) organization that works on behalf of our community to ensure that the quality and character of our community is preserved and enhanced. Unlike a typical homeowners association, GMIA does not own any property or facilities, and we do not have any paid officers or paid employees. Instead, we are served by an all-volunteer Board of Trustees elected by the membership.

Since 1938, GMIA has worked with county and regional governmental entities to help resolve issues that impact our community, such as: Transportation, traffic control, planning and land use, zoning, code enforcement, as well as crime prevention and law enforcement. In addition, our organization sponsors a variety of events to build community. Annual events include an Art & Garden Tour, Succulent Swap, Walk to the Top, Family Fest, Annual Dinner plus additional events from time to time.

There is strength in numbers! For our perspective to be clearly heard on issues impacting our wonderful, semi-rural lifestyle, we rely on a robust current membership. Plus, GMIA annual membership remains an affordable $18 per household to encourage everyone in our region to support our efforts..
