In 1969 John Sanden decided to leave the Midwest and a long career in Christian art, and try his hand at New York City and the world of portrait painting. Within months of arriving in New York, he was appointed to the teaching faculty of the Art Students League, had become affiliated with the city's principal portrait brokerage, Portraits, Incorporated, and had established a nationwide portrait clientele of the famous, wealthy and influential.
Sanden dedicated himself to a teaching career. He founded The Portrait Institute in 1974 and began touring the nation, teaching his ideas and techniques to thousands, who came out to hear him in classes as large as seven hundred at a time. He created a national correspondence instructional program. In 1979, Sanden launched the National Portrait Seminar, which grew to be the largest art seminar program in America. John Sanden is the author of four books on portraiture. With all of these demands on his time, he has managed to complete more than five hundred portraits of prominent figures in American public, professional and business life. His client list reads like a Who's Who of American education and industry. Popular columnist Pete Hamill, writing in the New York Post, August 15, 1991, said "John Howard Sanden is the closest we have in America to fit the old role of court painter."
