Delta Omicron Alpha

Delta Omicron Alpha (ΔΟΑ) was an American medical fraternity that operated from 1907 to 1917. This national professional fraternity was established at Tulane University and merged with Kappa Psi in 1917.

Delta Omicron Alpha was established in 1907 at the College of Medicine of Tulane University in New Orleans, Louisiana. Its founders created by-laws and a constitution, along with a ritual. The fraternity was managed through a Grand Chapter and held annual conventions.

Delta Omicron Alpha became a national fraternity with the creation of Beta chapter at Columbia University in 1908. In 1910, the Gamma and Delta chapters were established at the University of Tennessee and Southwestern University, respectively. Four additional chapters were added between 1911 and 1914. However, several medical schools closed or merged around 1915 because of a reduced number of students, resulting in two chapters closing and others struggling.

Delta Omicron Alpha merged with the medical and pharmaceutical fraternity Kappa Psi on November 17, 1917. Before the merger, the fraternity had initiated 1,063 members.

Delta Omicron Alpha's badge was a black enameled triangle, edged with jewels. It was decorated with gold Greek letters ΔΟΑ in the center. A gold star was above the letters, with a gold serpent below the letters.

The fraternity's colors were gold and white. Its flower was a white rose. Its publication was the Delta Omicron Alpha Quarterly.
