There actually was a Greek mob group in Houston ( http://usa.greekreporter.com/2009/06/06/greek-mafia-houston-inherits-greek-godfather/ ) . They apparently played a big role in kicking off the strip club business around there .

Anyways is there any info on the state of the US Greek mob in 2015 ? The Velentzas family and Philly Greek mob are listed as active on wikipedia , however there is no contemporary info available about them .
