Gordon is Emeritus Professor of Keyboard Studies at the USC Thornton School of Music of the University of Southern California.

As a student, Stewart Gordon studied with a number of prominent pedagogues and concert artists including Olga Samaroff, Walter Gieseking, Cécile Staub Genhart, and Adele Marcus.

Gordon's commercially issued recordings include works by Beethoven, Schubert, Schumann, Chopin, Scriabin, Ellis Kohs, Luis de Frietas-Branco, and the complete Rachmaninoff Preludes, although almost all of these are long out of print and only obtainable secondhand.

As a composer Gordon has primarily channeled his efforts into musical theater, and his shows have been successfully produced in New York City, Washington, D.C., Savannah, Hollywood, and Hawaii.

He is involved with book writer Robert Weller in creating a new musical based on the history of Palm Springs, California.
