What is a community foundation? The short answer: a not-for-profit, grant-making organization existing for the benefit of the residents in a given area. Community foundations also obtain and share information about needs in the community and identify charitable organizations who might best help fulfill those needs. 100WS is a component fund of Community Foundation for Loudoun and Northern Fauquier Counties (CFLNFC), which also helps us conduct due diligence on grant applicants and more. 100WS donors also benefit from fully qualified tax deductions because of our relationship with CFLNFC.
