Our People

MARK WENZEL, FOUNDER/WINEMAKER

The heart and soul of August Hill Winery and ISC, Mark is the visionary behind everything we do here, and his passion shines through. He is our award-winning winemaker. But a business owner does so much more. Working 14 hours days, no one works harder than Mark. And he loves every minute of it.

TERI WENZEL, FOUNDER
