Through its grantmaking program, the Rainbow Endowment works to promote health, visibility and full access to social, cultural and civic life for the lesbian, gay, bisexual and transgender (LGBT) community. A significant portion of the Endowment's annual funds are generated by the use of the Rainbow Card, a VISA credit created by Martina Navratilova. To date, the Endowment has distributed more than $2 million to organizations working on a national level to serve this underserved segment of our society, which receives less than 2% of all philanthropic dollars.
