Rosengren, who graduated from University of Central Florida in 1981, and his wife, Julia, recently gave $6.6 million to his alma mater, the largest gift in school history from an alum. The diverse group of beneficiaries, Rosengren said, reflect his and Julia’s interests. He’s a longtime fan of UCF football who majored in biology. She speaks nine languages fluently and became passionate about turtles after visiting a research facility. Rosengren, who grew up in Michigan, first joined the army in 1972 and then left in 1979 to attend UCF, where he was the cadet commander in the Army ROTC program and graduated in two years. He returned to active duty upon receiving his degree. Rosengren said the trauma of combat didn’t follow him home, but he knew others who had PTSD, including his older son, Josh, who served in the Iraq war during the mid-2000s. Rosengren later worked as a health-care administrator and lobbyist before starting his own company, Heritage Health Solutions, which provides health-care delivery and management services to government agencies and veterans. Rosengren, 65, and his wife now live in the Dallas area. Aside from UCF, Rosengren said they have given to several other causes, particularly those supporting veterans.
