After college, Arnold Chang went on to graduate school at University of California, Berkeley , where he studied under art historian James Cahill. It was through Cahill that Chang met the eminent Chinese painter and art collector CC Wang (). Chang followed Wang to New York, where he studied both painting and connoisseurship. In New York, Chang was hired by Sotheby's to help with a Chinese art auction, and afterward was immediately hired to head a brand new Chinese painting department at the auction house. Chang worked at Sotheby's from 1978 to 1993, at the same time continuing to paint and study under CC Wang. After leaving Sotheby's, Chang worked as Chinese painting specialist at Kaikodo in New York City from 1996 to 2006. This new job allowed him more time in the studio to focus on his own art.
