*Definition is here.  When asked about her favorite part of her last job, Alex Castro was quick to respond "the view".  An avid appreciator of both the beauties of nature and the essence of people, one of her favorite non-work activities is to head to the beach to watch the sunset. Alex is a Napa native with experience in the wine and sports training industries.  Arriving for her first day of work in the middle of the Covid-19 stay at home order, Alex met the team online.  Her upbeat energy and positive, infectious attitude are a great addition to our customer service team - both in person and online.
