The granddaughter of Koerner and daughter of Sheana Rombauer, Reagan grew up in Napa Valley and, like her mother before her, spent a good portion of her youth working at the family-owned winery. Her early experience at Rombauer included assisting with special events and the wine club, and jobs in the accounting department and the tasting room. A graduate of Boise State University, Reagan has worked in government contracting and real estate. She joined the winery in 2016 as Assistant Regional Sales Representative and was promoted to Sales & Marketing Support Manager in 2017. Reagans position at the winery shifted to Associate Brand Manager in 2019, where in her current role, Reagan conducts sales presentations and assists with sales program development; represents the winery at industry conferences, promotional and philanthropic events; and assists in identifying strategic market opportunities, including exports.
