"Shelter’s mission has always been bigger than any one individual," Santa Maria said. "I am deeply proud of what our team has accomplished together and am confident that Shelter is well-positioned for continued growth and impact. I remain fully committed to supporting a successful transition and ensuring the organization continues to thrive."

Shelter Youth & Family Services said additional information about the executive search process and transition timeline will be shared in the coming months.
