As a college student, Hewitt took an H&R Block tax course and described it as "the most interesting course I've ever taken." He began as a tax preparer, ascended the H&R Block management ranks and advanced to regional director, the youngest in the Block operating system. Hewitt managed more than 2,000 preparers in 250 offices in one of the firm's largest districts.
