When the partnership between galleriest Ronald K. Greenberg and John Van Doren ended in 2012, their blue-chip 57th Street venue, Greenberg Van Doren, shuttered. Van Doren has since teamed up with the former gallery's director, Dorsey Waxter. A name change and move to a swank Upper East Side townhouse followed. The new venture concentrates on secondary-market sales of historically established artists such as John Chamberlain, Sam Francis, Helen Frankenthaler, Hans Hofmann and Ellsworth Kelly.
