Leonard Day received a BA and MA from Fort Hays State University in art education and studio art. He is an art restorer and conservator, along with being an artist. His paintings are shown throughout many public and private collections. Day is also considered an authority on angels and lectures throughout the country. Day has also published many books including, "Diary of an Angel." In the book, Day stated, "From the pages of an angel's hand, we see how the divine entwined with the human, in the birth of a tiny child, and an angel followed closely. The child grew in the strength of spirit and tenderness of love, and the angel saw. Manhood did not alter his love for others, as those lame in spirit and blinded by fear sought his healing touch, and the angel marveled silently. Then, in the heat of anger, the fear he was taken aside and hung in shame before men, and the angel cried. Yet his spirit soared, and these words that both men and angels must know the words once written in Diary of an Angel."
