Some people love to work and don’t want to stop even after they turn 80 years old.

Why? “It is challenging and fascinating and never dull,” said Ronald N. Tutor, 83. He has run the Sylmar construction firm Tutor Perini Corp. for the better part of 60 years, and his only concession to age is that he’s down to working “only” 50 hours a week.

In this Special Report, the Business Journal interviews eight Angelenos, all 80 or over, who are still working hard every day.

One of them, Leroy Brown, even outdoes Tutor as far as longevity on the job. He’s 90 and has worked at the post office for 68 years. He does not plan to retire.

Tutor, on the other hand, has committed to giving up his chief executive role at the end of next year and then will be executive chair for two years before he retires. But he doesn’t seem enthused about it. 

“I have no idea what I am going to do with my time. That will be the real challenge.”
