Education: BS in Business Administration 1999

Certifications: QuickBooks® Online Certified ProAdvisor

When I went off to college, I was inspired to major in accounting, with the goal of achieving a CPA certification. This goal required 150 hours of undergraduate work, and 30 hours of accounting related courses.

While I was fortunate enough to land a job with a prominent construction firm and dedicated my professional skills and education to the success of the firm, my goal of becoming a CPA was put on hold.
