Gamma Sigma Sigma was founded on the idea of service. All chapters and colonies, collegiate and alumni, are required to perform a defined number of service hours during the year as set forth in national and chapter bylaws. Projects range from nationally sponsored causes to individual dedications, and chapters/individuals may be awarded for their efforts. Each member of the organization brings individual talents, skills and ideas to the organization, uniting in the spirit of service.

For more information please email the National Service Director.


Gamma Sigma Sigma’s National Service Program is designed to guide our sorority in accomplishing national service goals. It is developed around two Project I.M.P.A.C.T. areas, national service efforts, and service assistance for our members to enhance their service efforts. Take a moment to read through the National Service Program and learn more about some of our programs below.


At each National Convention, two special project areas are chosen by the delegation for special emphasis during the following biennium. These areas, known as Project I.M.P.A.C.T., encourage participation by all members, and help to establish relations with other national charitable organizations.

G.S.S. C.A.R.E.S.

In the event of a national or international disaster, Gamma Sigma Sigma National Service Sorority will respond with a special call to service – G.S.S. C.A.R.E.S. (Collaboration to Assist in Relief Efforts through Service). This is our initiative to help with relief when areas are devastated by any natural disaster / man-made disaster, and members decide to assist through donations, collecting items, or active volunteering in the area.

G.S.S. C.A.R.E.S. may include a special service project or service initiatives to address devastated areas until relief efforts have completed.

Members are encouraged to communicate their local efforts to the National Service Director for distribution through national communication lists.

The Service Assistance Program (SAP) provides financial assistance to chapters and colonies to support their service efforts in Project I.M.P.A.C.T. areas. Chapters/colonies must complete an application. Then, applications are approved by the National Service Director based on funding allocated for SAP for the biennium.

Chapters and colonies can complete the Service Assistance Program funding application to apply for funding to support service projects.  Visit the Service Assistance Program Page.


What is it?

In 2011, the sorority established Gamma Sigma Sigma National Day of Service as a national event. Gamma Sigma Sigma members are encouraged to participate in an act of service on or surrounding the sorority’s Founder’s Day, October 12th.

Who can participate?

All members are encouraged to serve for our National Day of Service. Feel free to invite your friends and family to join in your service as well.

What can you do?

Members are encouraged to serve within either of our Project I.M.P.A.C.T. areas Addressing Homelessness and Service to American Veterans and Active Military Personnel. We hope many members and chapters join together to serve within this Project I.M.P.A.C.T. areas; however, you are welcome to serve in areas outside of Project I.M.P.A.C.T.

Gamma Sig’s Green Initiative

At the end of the 31st biennium, Gamma Sigma Sigma approved plans to create a service plan for Environmental Awareness and Sustainability. The Sig Green Initiative focuses on ways the sorority can improve the environment through our service efforts as well as daily actions. Members, chapters, and colonies may use this document as a reference for resources related to service with an environmental focus. The information in this document may also be helpful with identifying individual ways members can be environmentally conscious in their personal lives. Read the Initiative.

Supporting Social Justice Through Service

Individuals and groups often address social issues through advocacy and awareness work. A good starting place with advocacy and awareness projects is educating yourself or members on the cause. In order to make other people aware, members must be knowledgeable, aware, and refer to correct information. Gamma Sigma Sigma members create awareness through hosting informational tables, forums, speaker series, walks, vigils, letter writing, and more.
