When Jim Ketai helped start the full-service real estate agency Bedrock six-and-a-half years ago, he had one mission: Never give up on making Detroit a better place for everyone. “I was born and raised in Detroit,” Ketai says. The suburbs, more specifically. Back then, people went to sporting events and plays, he recalls, but didn’t spend much time downtown before heading back home afterward. “I feel like my generation really missed out,” he says.
