SF Zoo names Cassandra Costello CEO after turbulent stretch

Between the lines: Costello formerly held roles at City Hall and in the public and nonprofit sectors, including at the San Francisco Travel Association and the city's Recreation and Park Department.

• Since taking the role, the zoo — operated by the nonprofit San Francisco Zoological Society — has reported a record January crowd of about 63,000 visitors and new events and programs aimed at boosting attendance.

Catch up quick: The zoo's previous leader, Tanya Peterson, retired in August after nearly two decades as CEO.

• She faced mounting criticism and pressure from Mayor Daniel Lurie and other city officials after an audit raised concerns over worker safety, poor animal care and financial mismanagement.

What's next: Under Costello's leadership, the zoo plans to improve its animal care and conservation programs and continue expanding discounted access for low-income families, among other initiatives.
