He has over thirteen years of experience in IT while working for such large enterprises as Hewlett-Packard, IBM, and The Home Depot.

He is well-known in sysadmin circles for co-hosting the PowerScripting Podcast, and heading up the PowerShellCommunity organization. He is also the author of a book titled "Managing VMware Infrastructure with PowerShell: TFM" published by SAPIEN Press in 2009. Previous to his career as a PowerShell guru, Hal was heavily involved in the Jabber / XMPP instant messaging protocol community as a member of the Jabber Software Foundation (now called the XMPP Standards Foundation).
