Laura Breyer, MS 

Born in Walnut Creek and raised in southern California, I returned to northern California after obtaining my Master’s degree in IPM from UC Riverside.  My first job in the industry was in the young R. H. Phillips’ winery lab, a position that stretched into three years of doing a little of everything a winery needs done.  I came to the North Coast after an internship with Mondavi Woodbridge and a short stint with Gallo in the Central Valley.  Working at Simi Winery in the viticulture department when Zelma Long was at the helm, and eventually starting my own business when mergers and changes altered the work environment.  I’ve been running Breyer’s Vineyard IPM Service since 1998 and have received California Department of Pesticide Regulation’s IPM Innovator Award.  As the IPM Field Specialist with the Sonoma County Winegrowers since 2000, I run the Grower Appellations Meetings.  In March of 2017 I became an accredited auditor for the California Code of Sustainable Winegrowing program.
