    For almost 30 years, Rhonda has helped people securely deploy, protect, and streamline their IT resources. She began her career in the US Navy where she spent 7 years as communications specialist with a top secret clearance. Later, as Sr. Security Analyst for an electrical utility company operating nuclear power plants, she discovered serious security flaws in software about to be acquired. She also consults for large customers showing how to quickly and cheaply roll out 50,000 Windows 7 desktops, but there's one thing that she loves even more than solving IT problems: sharing what she has learned with other people. Rhonda has a passion for learning products at the packet level and sharing that knowledge in her classes with clients large and small. She is a Setup and Deployment MVP, Desktop Deployment Product Specialist (DDPS), and MCSE on Windows NT, Windows 2000 Server, and Windows Server 2003. Along with teaching she presents at international conferences such as Tech Ed US, Tech Ed EMEA, MMS, Techdays Belgium, Ireland, and Slovenia. She is the only person to have won Speaker Idol on two continents (US and Europe) and is often in the top ten speakers, as recently as Tech Ed Belgium (out of 91 sessions). Rhonda has co-authored two books on Windows Server 2003 and Windows Server 2008 with Mark Minasi and regularly contributes articles to Windows IT Pro magazine. She is currently working on her first deployment book, titled Mastering Windows 7 Deployment.
