Rob Volk is a database administrator in the Atlanta, Georgia area since 2001, having worked in the wireless telecom, utility billing, and credit card processing industries. He started using SQL Server with version 6.5 and is very glad to have upgraded since then. He has presented at several SQL Saturdays and user groups in the US, and looks forward to his American jokes falling flat with the UK audience, which may prompt a poor imitation of The Parrot Sketch. In his spare time he accomplishes more than he does on the job, just don't tell his boss.
