My company, DifferenceWORKS is celebrating three years in business. Although women have been in the business world for decades, women are far from proportionally represented at upper levels in business. There is a compelling business case for gender diversity; businesses do better with women and men leading together. I set out to make a difference in this area. Birthdays are good times to review accomplishments; I chronicle what DifferenceWORKS has done in its first three years.
