Eta Rho Chapter was chartered in 1984 as the 183rd Chapter of Sigma Theta Tau International.  In 2009, Eta Rho Chapter celebrated its 25th Anniversary and was presented a plaque by the President of Sigma Theta Tau at the Biennial Convention in Indianapolis Indiana.  Some of Eta Rho Chapter's contributions have been to sponsor program educational events relevant topics to the nursing community, providing continuing education credits to professional nurses for relicensure and mentoring other nurse leaders in the community.
