As someone suggested research the various organizations, their founders etc. the best place to begin is with
www.npcwomen.org there are 26 member sororities listed with links to all their websites.
As a plug for Phi Sigma Sigma, I encourage you to check out their website at
www.phisigmasigma.org. Phi Sig was the first non-sectarian sorority founded. the following is from our history:
"The Founders of Phi Sigma Sigma came from a variety of religious and socioeconomic backgrounds. They wished to stay together as the group they had become while still in high school, but found that because of their varied backgrounds they all could not join one of the existing sororities on campus. They approaced the Dean of Women at Hunter College, and inquired about starting their own sorority, one that would promote open membership to all women of character regardless of background.
Phi Sigma Sigma was the first non-sectarian sorority, the only one open to diverse membership from its inception with a ritual not based in scripture. First in the minds of these ten women were the twin ideals which endure today. To the brotherhood of man and the alleviation of the world's pain, each Founder extended herself to her fullest capacity to live up to the mottoes the group chose. "
