*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.

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.

Rebekah Kramer, CPA is a partner in Brotemarkle Davis & Co. specializing in assurance services and business consulting. She is originally from Napa, California and is a Justin-Sienna High School alumnus. She is a graduate of Concordia University, Irvine where she majored in Business Administration with a dual emphasis in Marketing and Accounting. She spent three years working for a Southern California accounting firm before returning to the Napa Valley. While she may not find many opportunities to apply her SoCal yacht-counting expertise (she once had to count yachts docked in ports from San Diego to Newport), her diverse audit skills honed from working with customers in Oil and Gas, Manufacturing, and Real Estate are a big plus. Rebekah first stretched her entrepreneurial muscles when she founded a chapter of co-ed business fraternity, Delta Sigma Pi, at Concordia. She hopes to apply what she learned not only to her role as an auditor but also to some day opening an animal shelter. When she is not busy auditing, you might find Rebekah exploring a new trail or revisiting one of her favorite national parks – Denali in Alaska.
