The team at Mill Creek Vineyards is small but mighty! The winery is a family-owned, third generation business that was founded in 1965 by the Kreck family. However, six decades in business would not be possible without our entire team, who are all like family to us. Meet our family and wonderful team that bring Mill Creek Vineyards to life.

Bruce has been an invaluable part of the tasting room at Mill Creek Vineyards, providing excellent, laid-back hospitality for nearly 30 years.

Nicholas Munsell

Nicholas, the Assistant Winemaker at Mill Creek Vineyards, is the true hero of the cellar, doing "the real work" according to Jeremy. His superpowers? Wrestling barrels, taming grapes, and attention to winemaking details - all while making it look like a casual stroll through the vineyard.
