Welcome to #DOSProud Way,

Delta Omicron Sigma Alumnae Chapter (DOS) was chartered July 20, 1975 in Columbus, OH by eight magnificent women seeking to make a difference in the Greater Columbus area through community service and education. As a national leading service-based organization, it was important to our Chartered members to address the day-to-day challenges of the community through Sisterhood, Scholarship and Service.

For more than 40 years, Delta Omicron Sigma has become synonymous with excellence, leadership and youth development. Our Chapter exudes talent of more than 30 members ranging from educators to mental health counselors, family physicians, business managers to non-profit directors and more. We advise three Undergraduate Chapters at The Ohio State University, Ohio University and Wilmington College. We mentor girls ages 12-18 through the Rhoer Club and advise the newly chartered Philo Affiliate known as “friends” of the sorority.

We proudly serves approximately 2,000 children and families annually through food assistance programs, parenting education, local advocacy, breast cancer awareness, Toys for Tots and more. Through in-kind support and monetary donations, we reinvest a little more than $2,500 to support Columbus families and residents every year.

Our Chapter members and Affiliates are recipients of dozens local and regional awards, including the NPHC Columbus Chapter and Columbus City Schools.

In conjunction with the Divine Nine sororities, hosted the first-female led Townhall Meeting titled, “Golden Alert Townhall Meeting - #SayHerName” in honor of our fallen Soror Sandra Bland.
