Do all arboriculturalists drink green tea? Or is it only the crew of Barrett Tree Service? Founder and owner Winthrop Barrett laughs, “Yeah, we’re always drinking the green tea.” It’s by no means a profession-wide tradition, he explains, but it does serve a purpose. “It’s a performance drink. It gives you a nice steady buzz, whereas coffee brings you up and then you crash.” And when you’re in a business like tree care, you want an even keel.
