Explore Our Organization
Founding Organizations
At the heart of Keystone are our founding organizations, Glenkirk and Search360, two nonprofits with decades-long legacies of supporting people with intellectual and developmental disabilities (I/DD). Together they created Keystone as their parent organization, providing shared governance and an operational backbone that strengthens their ability to deliver on their missions for the long-term. Keystone serves as their shared home, offering centralized infrastructure, strategic leadership and collaborative thought partnership.
Advocacy
Our deep expertise in the I/DD sector, grounded in the work of our founding organizations, guides our efforts to strengthen the community-based system that supports people with disabilities. Through coordinated advocacy, we help shape policies and push for adequate funding that supports the success of nonprofits and the well-being of the people and communities they serve, building stability, capacity and long-term impact across the sector.
Keystone Shared Services
Keystone Shared Services delivers a comprehensive, integrated platform of critical back-office functions, including finance, HR and IT. More than operational infrastructure alone, we act as a true extension of your team, providing ongoing thought partnership that integrates insight, strategy and collaboration. Built, proven and continually refined within our own family of organizations, our platform is designed to create capacity, financial wellness and mission sustainability. We bring the same disciplined approach to every organization we serve, shaped by the challenges and realities we all navigate as nonprofits.
Mission + Strategy
A leading thought partner in strategic advising and merger and partnership support, Mission + Strategy is our dynamic consulting division focused on strengthening organizations across the nonprofit sector. We combine deep nonprofit expertise, a collaborative approach and a commitment to client goals to deliver practical, strategic solutions through project-based engagements. Grounded in Keystone’s shared purpose of strengthening the nonprofit landscape, Mission + Strategy helps organizations navigate challenges and opportunities to build capacity and resilience.
A Message from Our Co-CEOs
A Legacy of Partnership
Keystone Alliance was founded in 2009 with the simple but powerful idea that nonprofits are stronger together. Our founders, Glenkirk and Search360, are two community-based organizations with decades of experience serving people with intellectual and developmental disabilities (I/DD). Rather than operating in isolation during a period of fiscal austerity in Illinois, they joined forces to create a new nonprofit entity designed to serve their collective needs. Under this shared home, they consolidated the back-office functions of finance, HR and IT into one collaborative structure. Through this partnership, both organizations have expanded their capacity, achieved sustainable mission impact and built a stronger advocacy voice while preserving their unique identities and deep community ties.
A Proven Model for Resilience
What began as a pragmatic response to operational volatility has evolved into a living example of how nonprofits can thrive together. Through 17 years of real I/DD provider experience, we have refined Keystone Shared Services into a proven model for effective financial stewardship and organizational resilience that offers sector wide value to other nonprofits.
Igniting Transformation Through Collaboration
As we continue to adapt to meet the new challenges facing our sector today, we are excited to reintroduce ourselves with an evolved brand as we expand our reach to support a broader community of mission-driven organizations. When nonprofits turn to Keystone Shared Services for operational support or to Mission + Strategy for strategic advising and partnership guidance, they gain the full benefit of Keystone Alliance’s collective expertise and our commitment to strengthening nonprofit impact. While we remain firmly rooted in supporting our founding organizations, we are thrilled to offer this specialized expertise to the wider nonprofit world.
Our refreshed brand identity and soon-to-come, new website will better reflect our vision of a future where nonprofits join together to become a vital force in creating more resilient and equitable communities for all.
Stronger together,
Greg Petersen, Kim Berenberg, and Cory Gumm
