Lisa Akrawi is a graduate of Walla Walla University where she earned a BBA with a concentration in accounting and a certificate of business analytics. A former Napa Valley resident, she was drawn to accounting by an interest in numbers, organization, and balance.  She sees accounting as a specialized language to learn and apply.  Her BDCo title, 'Virtuoso', is word-play on the importance of integrity in the role of a public accountant and the artistic endeavors in her personal life. She became a certified makeup artist while obtaining her BBA and continues to make time for creative activities, even when work gets busy. This is her way of maintaining time management, critical thinking, and work-life balance.  From her Orlando, Florida home, Lisa enjoys peaceful mornings, summer storms, and a sunny house full of pets and plants.

Dawn Marshall is a Napa native.  She briefly left the Napa Valley for a sojourn to Miami, Florida but returned to Napa to begin her professional career.

She is a two time recipient of “Award of Financial Reporting” by the Government Finance Officers Association.

As a young woman, Dawn went off to purchase her first automobile, a Renault, at a local Napa automobile dealer.

*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.
