Two of Connecticut’s largest nonprofit trade associations are joining forces and will become one organization by Feb. 1.

The Connecticut Association of Nonprofits and the Connecticut Community Providers Association will merge and become the Connecticut Community Nonprofit Alliance. The new alliance will include 600-member nonprofits.

The mission of the new organization will be to advocate and build capacity for community-based, nonprofit organizations that strengthen and sustain healthy communities.

“By merging our two organizations, we make our voice stronger, and we can more effectively advocate for the half-million individuals our members serve every day, in every city and town in Connecticut,” Andrea Ferrucci, CCPA board chair, said in a statement. “Working together, we can also achieve economies of scale, expand member training, group purchasing and other business opportunities, and maximize limited state dollars.”

The combined associations will represent nonprofit organizations focused on providing human services, health care, education, anti-poverty programs, housing, recreation, and arts and culture. The combined membership will employ more than 100,000 individuals, and spend about $3 billion each year.

“Nonprofits are an essential and integral part of communities across the state and contribute to the quality of life that people in Connecticut hold so dear,” CT Nonprofits’ Board Chair Peter DeBiasi said in a statement. “This merger creates a new organization that will be a more robust and effective support and voice for Connecticut’s nonprofit community and the people we serve.”

Membership in the new association is open to all Connecticut nonstock, nonprofit corporations whose missions are consistent with that of the new association.
