This report and related WNY Asset and Gaps/Needs Map identifies the capacity building needs and assets of nonprofit organizations in a nine-county region of Western New York (WNY). Commissioned by the Western New York Nonprofit Support Group (WNYNSG), CGR partnered with the Community Health Worker Network of Buffalo to conduct the study, which included best-practice research, a survey of nonprofits, interviews, and focus groups. Special emphasis was placed on capturing and highlighting the voices of frequently marginalized groups that often do not have access to traditional capacity building resources. Capacity building challenges in WNY included fundraising and development, marketing and communications, board governance, recruiting and retaining diverse staff and board members, and using data for evaluation and strategic learning. Assets included dedicated staff, networks of support, and grass-roots organizations’ ability to authentically engage community. The project also identifies participant-generated ideas for addressing capacity building needs. Data in the report and interactive map serves as a tool for the WNYNSG to engage the nonprofit community and inform planning and collaboration among their foundation members.
