Houston has an interesting leadership platform that I know a few other big zoos have too. They have a separate CEO and zoo director. Contrary to the title of this thread, Lee Ehmke is NOT the new zoo director. That will continue to be (as far as I know) Rick Barongi (formerly of Disney Animal Kingdom). Ehmke is the new president and CEO, replacing Deborah Cannon. I am sure they will make a great team, but as an outsider with little knowledge of the business world, I am not entirely sure what the different roles of a director and CEO are. I am also not sure why some zoos feel the need for both while others are fine with just a single director. Any thoughts?
