(Portland, OR) -- The Oregon Zoo has a new director. The zoo announced yesterday that Heidi Rahn will replace Don Moore, who retired last year after a 45-year career in animal welfare science and wildlife conservation. Rahn previously worked at the zoo from 2013 to 2018 as head of Metro's 125-million dollar zoo bond program. Under her leadership, the zoo opened some of its most iconic areas including Condors of the Columbia, Elephant Lands, and the Education Center.
