As you will see from the following biographies, Allied Grape Growers' staff is made up almost entirely of people who come from grape growing backgrounds. Most of our employees were raised on or around agricultural operations which produced grapes. There are no better people to serve the owners (growers) of a grape growers cooperative than those that have grape growing experience themselves, knowing the challenges that growers face.

North Coast Grower Relations:

He attended Northeastern University where he achieved a Bachelor's Degree in Music Business and spent some time in New York City developing record labels and promoting and marketing new artists. It wasn't until about 2008 that Matt, upon moving to the west coast due to his wife's job transfer, really discovered his true passion in the wine business. Upon arriving in California, Matt went to work for Treasury Wine Estates as an on-premise manager and wine club coordinator for their San Francisco tasting room. He subsequently held similar positions on the retail side of the business at well-known wineries such as Chateau Montelena in Calistoga and Round Pond Estate Winery in Rutherford. But at Chateau Montelena, Matt really began dialing in on his true passion within the industry, that being the production side. This interest drove Matt to pursue and obtain an Associate's Degree in Viticulture from Santa Rosa JC in 2013 and begin working in the vineyard side of the business, with the desire to eventually work in Grower Relations. Prior to being hired at AGG, Matt has been managing vineyards and doing viticultural consulting.

North Coast Grower Relations:
Kevin Rogers (2016)
Although Kevin was born and raised in Chicago, Illinois, his passion for wine was instilled in him while he was a teenager, making wine with his Sicilian grandmother in her basement. As an adult, Kevin began making trips to Sonoma County to learn more about grapes and wine and realized that his passion really lay with the wine industry. In 2000, Kevin moved to Sonoma County to begin his career in the wine industry. He began working that year at Ferrari-Carano Vineyards & Winery in Healdsburg. His path there took him from the tasting room to the cellar and finally, to the viticulture lab, where he helped cover about 1,500 planted acres over six different appellations. During this period, Kevin completed the viticulture program at Santa Rosa Junior College. By harvest of 2005, Kevin began working at Beaulieu Vineyards (BV) in Napa Valley. He began there as a Harvest Enologist and ended his time there as Assistant Winemaker. By the end of 2009, Kevin was working on his own wine label (Nico Wine). He continues to produce fine California wines under the Nico Wine label, and enjoys offering unique selections including Dolcetto, Fiano and Greco along with more traditional varieties such as Barbera and Grenache. In 2014, he went back to work for Ferrari-Carano as their Viticulturist, and then joined Allied Grape Growers to help with the 2016 harvest. It didn't take long for AGG to figure out Kevin was worth keeping around in a more substantial role for our North Coast growers, so following harvest Kevin was offered and accepted a year round role in grower relations.
