He attended Mississippi Heights Academy at Blue Mountain. After graduating from Mississippi College in 1915, he became the superintendent of the high school in Derma. After World War I, he went to Eupora as superintendent and later became superintendent of Leland Consolidated School. In 1933, he became JPS superintendent. During his administration, the Jackson Municipal Boys' Band was organized and the Reserve Officer Training Corps was established at Central.
