John Lesak is a Principal at Page & Turnbull in Los Angeles,
where he specializes in in the preservation, rehabilitation, repair, and reuse of historic structures. His work includes the adaption of historic modern office buildings, 1970s concrete structures, and a 1960s library into The Cheech, a museum for Chicano art in Riverside, California that opened last year to house the collection of actor Cheech Marin. Unfrozen and Lesak chat concrete, the broad meaning of historic preservation, and of course, the Cheech – the man and the museum.
