Alpha Kappa Alpha Sorority, one of the largest women’s organizations in the world, recently inducted several high-profile honorary members at a private ceremony.

According to a press release issued by the organization, Dr. Helen D. Gayle, president and CEO of Care USA, and media mogul Sheila C. Johnson became members of the storied organization, which was founded at Howard University in 1908.
