Rob Volk is a database administrator in the Atlanta, Georgia area for the past 10 years, 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.

In his spare time he accomplishes more than he does on the job, just don't tell his boss.
