Big Brothers Big Sisters of Tampa Bay has named Robyn L. Ostrem as its next chief executive officer. She will begin her new role on August 4.
Ostrem has more than 25 years of nonprofit leadership experience and a long-standing commitment to youth development. She most recently served as senior vice president of operations at the Tampa Metropolitan Area YMCA, overseeing a $31 million portfolio across 14 locations.
Her new position marks a return to the Big Brothers Big Sisters network. From 2000 to 2013, she led the McHenry County, Illinois, affiliate as executive director and volunteered as a mentor during her tenure.
“Big Brothers Big Sisters is where I found my purpose,” Ostrem said. “I’m honored to return and help write the next chapter—one filled with connection, impact and opportunity for every child.”
Big Brothers Big Sisters of Tampa Bay supports more than 2,500 children, each year, across nine counties through one-on-one mentoring, group programs and targeted initiatives designed to build confidence and long-term success.
Ostrem succeeds outgoing CEO Chris Letsos, whom the organization thanked for his service.
