21. Rick Hamada, COO, Avnet
No one has more experience navigating the topsy-turvy, insanely competitive distribution marketplace than Hamada. The 26-year Avnet veteran has made sure that the company gets its partners all the tools and support they need to be successful. That has meant an all-out push into higher-margin territory, including government and health care. Key to Avnet and its partners' success has been Hamada's ability to drive tight relationships with vendor partners.
