Meet our Team

OSG Co-founder and chair Paula Manion – along with spouse Joe Manion – launched OSG after a fruitless search for housing options for the couple’s adult son, Mike, a person with autism (and the eldest of their three children). In a bid to dismantle barriers impeding Mike and other adults with DD, Paula and Joe realized that a combination of affordable, independent housing near public transportation and appropriate supports – such as a live-in aide, roommates or social worker check-ins – would set the stage for a more complete integration of a disabled adult into the community. A Pediatric Nurse Practitioner by training, Paula resides in Northern Virginia, not far from Mike, who now has his own apartment in an OSG community, a good job and a rich social life.

Get to know the dedicated group of people behind OSG. Each brings a passion for the disability community, and many are parents of adults or children with disabilities.

Josue Amaya

Josue (pronounced ho-SWAY) can always be found out and about with OSG community members, whether it’s picking up trash with the gang on Teddy Roosevelt Island or counseling an Ovation resident one on one. Service comes naturally to Josue, who has coached high school rugby and supported refugees and unhoused people, among other roles. In his spare time, Josue loves live music, sampling Korean BBQ and biking around his hometown of DC.

Two decades of event planning have honed Joy’s organizational prowess, while her work in special education –as an advocate for her kids as well as other families’ children – translates to lived experience urging the education community – and the world at large – to envision and effect bold and unapologetic inclusion for neurodivergent people.
