When Adam Witty was eight years old, his father was laid off from his job at AIG.
"Rather than find another job, he decided he was going to start a company," recalls Witty, who is now 29. What started out as a two-man health care credentialing company in the Witty garage became Med Advantage, a 150-person organization, in just a few years.
