Erin spent 12 years in the public accounting sector as a Certified Public Accountant. She began her career in Chicago in the audit practice of Arthur Andersen before transitioning to the audit practice of Deloitte.

While working for Deloitte, Erin transferred to the Cambridge, England, office. In Cambridge, she expanded her portfolio by working on smaller start-up companies. After five years with Deloitte, Erin moved to Ernst & Young in Cambridge and continued as a manager in their audit practice where she spent the next six years.
