His first New York production was a modern version of Shakespeare's As You Like It in 1945, imported to the President Theatre from a production at the University of Washington in Seattle. According to The New York Times, Elson's sets received more critical praise than the production did.

Elson also designed for opera, designing productions for the Central City Opera in Colorado (Fidelio and Martha in 1947) and the New York Metropolitan Opera (The Flying Dutchman in 1950, Lohengrin in 1952, Don Giovanni in 1953, Norma in 1954, and Madame Butterfly in 1958). For City Center Opera at the New York State Theatre, he designed Dialogues With the Carmelites in 1968.

In 1950, Elson designed sets for the Katherine Dunham Ballet; he was assistant art director on one film, A Star Is Born, in 1954. In addition to his long design career, Elson taught scene design at Hunter College at the City University of New York, the University of Oklahoma, and the University of Iowa; he was cultural attache for the State Department in Southeast Asia in the 70s and edited several volumes of technical writing on stage design.
