DETROIT -- Cleveland Cavaliers owner Dan Gilbert, who is the Quicken Loans founder and chairman, is slowly returning to work eight months after he had a stroke.

Gilbert, 58, returned to his Detroit office early this year. He's there one or two days a week, using a wheelchair and accompanied by a service dog named Cowboy. He also spends three or four hours a day working with physical and occupational therapists at his home.

"When you have a stroke, here's the problem with it: Everything is hard. Everything," Gilbert told Crain's Detroit Business in his first interview since the stroke. "Like, you wake up, getting out of bed is hard, going to the bathroom is hard, sitting down eating at a table is hard. You name it. You don't get a break. You're, like, trapped in your own body."

Gilbert is scheduled to give his first public speech since the May 25 stroke this Friday at the Crain's Newsmakers of the Year luncheon in Detroit.

It's a change of pace for the hard-charging executive, who also owns the American Hockey League's Cleveland Monsters and the NBA G League's Canton Charge. Right before his stroke, Gilbert was texting Michigan's governor about a deal to get long-term funding for road repairs.

Gilbert was hosting a party just before Memorial Day when his vision seemed suddenly blurry. His wife and a physician friend persuaded him to go to the hospital after he started showing other signs of a stroke, including facial asymmetry, arm drift and speech difficulty.

Gilbert said he had a blood clot in his carotid artery that was cutting off the blood supply to his brain. Doctors implanted seven stents inside his carotid artery to open the blood vessel.

"If that artery was blocked more minutes than it was, it would have been much worse," Gilbert said.

Gilbert spent eight weeks at a rehabilitation center in Chicago last summer. He is able to walk with a cane but still struggles to move his left arm.

Gilbert said his current priority is the construction of a skyscraper in downtown Detroit. His real estate company, Bedrock Detroit, broke ground on the building in 2017.
