Finance Intern

March 2023 - August 2023 Seattle, WA
“The up-close view of what it takes to run a small business is one of the many unique pros of this job. I had high flexibility in my focus areas, which exposed me to many departments that let me experiment with what type of work I enjoyed. The workplace environment is collaborative and encourages questions. My supervisors were patient, kind, and excited to help. Despite his busy schedule, the president of the company consistently made time to meet with me, offering advice and addressing my questions. This commitment exemplifies the company's emphasis on humility and the nurturing of young professionals.”
