EarthLink President and CEO Garry Betty was diagnosed just days ago with a serious form of cancer, and he will take a medical leave of absence in order to tackle the disease head on.

“Garry is a fierce competitor and has the determination to beat this disease,” said EarthLink founder Sky Dayton.

Betty, at one time the New York Stock Exchange’s youngest listed CEO, joined the EarthLink team in 1996 and has earned tremendous respect and recognition among the Internet, financial, and business communities. He is now earning support as he takes on his newest challenge — cancer.

Mike Lunsford, executive vice president of voice and access at EarthLink, will act as interim CEO and will immediately take on Betty’s daily responsibilities.
