Megan O’Donnell

Direct Sales Manager

Megan O’Donnell

Napa native Megan O’Donnell grew up with a love of great food and a deep appreciation of the beauty and culture of Napa Valley. Naturally, she developed a passion for the world class wines the valley produced.

With a diverse background in retail she began her career in wine sales and marketing in 2002 as the Director of Hospitality for Ballentine Vineyards. During her three years at Ballentine, she opened their retail room, developed a successful direct sales program, managed all aspects of their hospitality and events program and launched their wine club.

Classes at Napa Valley College in General Viticulture and Wines of the World inspired her to learn more about the appellations and unique wine styles of Napa Valley producers and she took the opportunity to gain more knowledge first hand by working with collective tasting rooms in St. Helena and Rutherford.

In 2005 Megan joined the Hill & Wollack Wine Estates team and currently manages all aspects of the Tetra direct sales program and the hospitality and retail program at Silverado Trail Wine Studio - where Tetra is both produced and sold.

Outside of wine sales, Megan is passionate about raising her four year old son Joseph, trying new restaurants (and dining in her many favorites) as much as she can, and spending time outdoors hiking and exploring the wonderful California scenery from Dillon Beach to Muir Woods with her son.
