Motto: “To exercise our abilities to a maximum so as to minimize our disabilities, that we may live most and serve best.”

Delta Sigma Omicron (DSO) is a rehabilitation service fraternity whose members originally were students with disabilities on the University of Illinois campus. Membership is now open to all persons enrolled in the University of Illinois, Alumni and field members with an interest in ensuring that qualified individuals with disabilities are afforded an equal opportunity to participate in, and benefit from, the curricular, co-curricular and vocational opportunities available at the University of Illinois at Urbana-Champaign.

Delta Sigma Omicron has a long, proud, and distinguished history. It was founded in 1948 and incorporated in 1949 in Illinois, long before individuals with disabilities received any public or media attention and long before there were any meaningful State or Federal laws. Delta Sigma Omicron, through its programs and membership, played many significant roles in bringing about some of the legislation and benefits that now exist.

It was the first Fraternity dedicated to education, research, and service in rehabilitation, made up entirely of achieving individuals with disabilities. It pioneered in many areas of concern such as education, employment, accessibility, transportation, sports and recreation on behalf of those with disabilities.

Since its founding, Delta Sigma Omicron has contributed significant funding to charities aiding persons with disabilities. Finally, its members have conducted, participated in and have been subjects for research furthering rehabilitation.
