On Company Culture: It’s been about culture for us. I’m not going on jobsites, yelling at our crews, giving them a hard time. I’m going to jobsites and working alongside them, trying to make their lives a little easier. We like to joke that we’re a company where the electrician has the architect’s phone number. Who else does that?
