In June 1950 White began teaching at the Workshop School of Advertising and Editorial Art, an institution dedicated to training artists to work in the commercial advertising world. Run by the designers A. F. Arnold and Milton Wynne, the school advocated for both technical expertise and the moral responsibility of the artist to be accountable for the content and uses of their work. White was one of two black faculty members on the staff of the school, where he likely taught life-drawing courses.
