Years back I called a phone number linked to norman birmingham and spoke to a man with a nj 'wiseguy' accent...he said he was birmingham but I have no idea if it were truly him or not.
I don't have the number now but I think I found it by searching around for norman j birmingham and won-gil choe as relates to a company which was called netcert at the time of the information...choe and birmingham were listed as officers of the company...keep looking for information such as that which I have linked to..look for press releases and look for birminghams number listed at the bottom as 'investor relations' if I'm not mistaken....good luck..
