Cultivating Our Sisterhood International Association, Inc. (COSIA) is a 501(c)(3) nonprofit whose mission is to cultivate a sense of sisterhood among women and to enhance the lives of those whom they support. At COSIA, we develop supportive networks that are not limited by age, ethnicity, sexual orientation, or religion; utilize these networks as resources to produce affordable events and programs that promote team-building and the pursuit of personal and professional life goals and objectives; and support through fundraising and volunteer activities socially conscious initiatives and programs that benefit girls and women from underserved communities.
COSIA members support the work and mission of COSIA through committee service, financial gifts and pledges. Are you a woman, age 18 or older, who is willing to share your resources, gifts and talents with us for worthy causes? If so, join COSIA today.
