Dave is a logistics manager with good engine mechanic skills. He keeps the Zodiacs in working order and drives them as a naturalist guide. Although he earned a degree in industrial engineering, he worked instead as an intern at Walt Disney World, at a ski resort in Colorado, and as a stock broker on Wall Street. He finally found his calling when he became an Expedition Leader, guiding small groups around South America, Africa and Asia. He has traveled from the Kazakh Steppe to the Sudanese Sahara to the Altiplano of Bolivia. Now in his fourth year with Quark Expeditions, Dave has his compass set on the Polar Regions.
