My Current focus is on Server Based Computing and Virtualization. I am currently the Sr. Network Engineer for Rush University Medical Center in Chicago, IL with a Citrix implementation serving 14000 users (or customers as we have to call them now a days :-)). Prior to that, I was the Server Based Computing Architect for General Growth Properties, the second largest shopping mall owner and operator in the world.

I have co-authored many books including:

• “Citrix CCA MetaFrame Presentation Server 3.0 and 4.0 (Exams 223/256) (Exam Cram)” by Que Publishing
• “MCSE Designing Security for a Windows Server 2003 Network: Exam 70-298 Study Guide and Dvd Training System”
• “Citrix MetaFrame XP Including Feature Release 1” by Syngress Publishing

I was also the Citrix series trainer for CBTnuggets.com and developed the first Citrix MetaFrame XP 1.0 FR1 & FR2 training videos 

I am also a Contributing Author at WindowsITPro Magazine, Techrepublic.com, Certcities.com, Cramsession.com and Brianmadden.com
