In 1931, the Unity Training School was organized, and Mr. Ingraham was placed in charge of the first training class held at Unity Farm. He was with Unity as a worker and field lecturer from 1928 through 1935. For the next ten years he worked independently, continuing his research work into the teachings of ancient and modern religions. For three years he taught at the Institute of Religious Science in Los Angeles.
