Since Sellers stepped down from active leadership of Wentworth in 1923, the position has been held by four of his descendants: son Sandford Sellers, Jr. (1923-1933), son James M. Sellers (1933-1960), grandson James M. Sellers, Jr. (1973-1990) and great-grandson William W. Sellers (2008-2013).
He served on the National Safety Council from 1942 to 1943, as headmaster of the Elgin Academy from 1943 to 1945, as superintendent of Morgan Park Military Academy from 1945 to 1949, and as Director of Education for the 4th U.S. Army Corps in San Antonio, Texas from 1950 to 1962.
He is the fourth generation of his family to head the school, following his great-grandfather Sandford Sellers, who led Wentworth from its founding in 1880 until 1923, his great-uncle Sandford Sellers, Jr. (1923–1933), his grandfather James M. Sellers (1933–1960), and his father James M. Sellers, Jr. (1973–1990).
