Thompson, Chairman of the Board, Illumina (former Chairman of the Board, Microsoft) I first met Roy in 2000 and he instantly embraced the Rainbow PUSH Coalition's campaign for equity, diversity and inclusion in Silicon Valley and the tech industry. He talked to me about his personal experience, where his peers in several companies rose to the highest heights while he was stifled. There was no talent deficit, but an opportunity deficit.
