The company's statement did not indicate where Gilbert was hospitalized, but The Detroit News reported the 57-year-old was admitted to Beaumont Hospital, Royal Oak in suburban Detroit.

"Early this morning, Dan Gilbert sought care at a local hospital after experiencing stroke-like symptoms," Quicken said in the statement.
