For several years now, CAMH senior curator Valerie Cassel Oliver has eschewed fickle fads in favor of the quiet, steady promotion of serious artists like Susie Rosmarin, Trenton Doyle Hancock, Jae Ko, Nathaniel Donnett, Benjamin Patterson, Robert Hodge, Sanford Biggers and Jason Villegas. The art world can be a vast, contentious and capricious place, and it takes a well-seeing eye to avoid the flavor-of-the-month distractions. With her commitment to local artists and her discerning taste, Cassel Oliver has energized the institution.
