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.
