Story
Tagline
Exchange MCSM & MVP, Author, and Blogger
Introduction
Microsoft Certified Solutions Master and Office Servers and Services MVP in the San Francisco bay area. I hold multiple certifications including MCITP:Enterprise Administrator and MCITP:Enterprise Messaging Administrator, MCSE:Messaging and CISSP.
 
I am the author of The EXPTA {blog}, as well as a published author, contributing writer, and technical editor for more than a dozen technical books and other publications.

I work primarily with Microsoft cloud and on-premises solutions(Exchange Server, Active Directory, Office 365, etc.). I also work with various other platforms and products, usually in the form of migrations. 

Microsoft is not a "religion" for me. They simply provide the best products, in my opinion, and I like to work with the best.
