Philanthropy Serving Organizations (PSOs) are networks of organizations and individuals who practice philanthropy. Typically, the members of PSO include private, corporate and community foundations; corporate giving programs, United Ways; and other federations. Many PSOs also have individual donors and tax-supported entities (such as state arts or humanities councils) in their membership.
Each Regional PSO serves a specific geographical area. Our members are clustered in western Pennsylvania, but we welcome members located at a distance who are interested in connecting with those in our region.
