Our Team

 

Jan Krupp 
Founder

An oenophile with a green thumb, Jan was a hobby winemaker and suburban farmer in the San Francisco Bay Area for 15 years. Though a full-time doctor, in his spare time, he grew everything from green beans to gooseberries and produced beautiful wines, using his driveway and basement as a makeshift winery.

While still a full-time doctor Jan moved to Napa in 1991, to start growing things on a larger scale - beginning with a 41-acre vineyard around his new home. With his brother Bart, he would develop two more vineyards, including the iconic Stagecoach Vineyard. In 1998, he sold his medical practice and the following year, Bart and Jan founded the winery.
 

Desiree O’Donovan
Winemaker

Raised in the California Wine Country, Desiree O’Donovan was studying for a career in dentistry when a part-time job at a local winery opened her eyes to her true passion. 

After completing internships at several notable local wineries, she began her career at a Napa custom crush facility, where she became the Assistant Winemaker. There she had the opportunity to learn different winemaking styles and work with many boutique wineries, including Krupp Brothers. Impressed by her talent and dedication, Desiree was one of Dr. Krupp's first hires when Krupp Brothers had the opportunity to move to its own winery facility.

Her energy inspires people everywhere.

Fredrick Umfress
Tasting Room Manager

With a vivacious personality and a love for entertaining others, Fredrick always knew he wanted to pursue a career in hospitality. Born and raised in the Bay Area (with brief stints in England and Texas as an Air Force kid), he was brought up with an appreciation of food through his Italian heritage.

When not crafting one-of-a-kind experiences for guests, Fredrick can be found at home continuing his wine education, playing old records and spending time with his family.

Knowing that each vintage was painstakingly crafted, sparing no expense, gives her great pride in sharing the Krupp Brothers story and wine. As the wine club and communications Manager, she sees her role as not only sharing Krupp Brothers with those who love the wine as much as she does, but also making sure that every club member experience is as exceptional as the wine we make.
