But the variety also can make his life a bit topsy-turvy. The tough part is the way his schedule can change at a moment's notice.
"You never really know what your plans will be for the day. If there's a problem with one of the schools, I rearrange my schedule to be there. If there's a fire on the weekend, they call me," he says.
"And if there's a bus accident, it's absolutely necessary I be there immediately. Those are probably the most stressful."
Still, Seymour rarely looks anything but perfectly calm. Every detail's in place, from his flawless manners (he hurries to hold coats and open doors) to his neutral blue suit and tasteful paisley tie (a gift from his daughter, he emphasizes).
He's a simple person, serious, Seymour says. He enjoys gardening. He's a lifelong member of the Presbyterian Church. He always orders the same dinner in restaurants - a New York strip steak, baked potato and salad.
The occasional upsets of life leave Seymour unruffled. "I may occasionally get a little tense at work, but in 32 years, I don't think I've ever lost my temper," he says.
A few years ago a thunderstorm knocked out the electricity during a board meeting. Seymour helped the meeting continue by procuring flashlights. Calmly.
The evening was, he recalls, "a bit unusual." But just part of the job.
"If you're going to do well, you must have total commitment to what you're going to do," he says. "Then you enjoy it, and it's worthwhile."
Sue Petty, a receptionist at school headquarters, has watched Seymour at work for nearly a decade.
"He's a fine gentleman, that's what he is," she says. "He always nice like that. He always does the right thing."
