"She has served immeasurably in her capacity as studio instructor, director, mentor and celebrated performer," Preston wrote. "I had the great privilege to direct her as Kent in CalArts' Center for New Performance's (CNP) production of King Lear. Her extraordinary performance is one that I cherish and is vividly remembered by all who experienced it. Mary Lou's profound love of Shakespeare and deep care for her students were felt by all. She will be sorely missed."
