Our History

OSG began in 2019 with a bold vision: to create inclusive communities where adults with developmental disabilities could live with dignity, choice, and connection. Inspired by the Main Street model and guided by founders Paula and Joe Manion, the organization—originally known as City Center NoVa—quickly evolved from a centralized concept into a growing network of neighborhood-based communities.

OSG's Breakthrough

OSG’s breakthrough came through a partnership with True Ground, a Northern Virginia developer, which opened the door to Gilliam Place—our first inclusive housing site and proof of concept. What began as a few affordable units became a thriving community, where neighbors with and without disabilities share meals, make art, ride the bus, and build lives together.

Today, OSG supports residents across seven apartment buildings—and growing. With each new site, we deepen our commitment to interdependence, self-determination, and the rights affirmed by the 1999 Olmstead Decision.

Anything is Possible

Our model is not just possible—it’s replicable. And our success proves what we’ve always known: with the right supports and partnerships, adults with developmental disabilities can lead full, connected lives in the heart of the community.

The 1999 Olmstead Decision was a pivotal moment in the community living movement, mandating that individuals with disabilities have the right to live integrated lives in their communities rather than being segregated in institutional settings. Learn more here.
