Welcome

Welcome to MitchelSellers.com, this is my personal blog/commentary site and is in no way, shape or form affiliated with my employer.  On this site you will find a few key pieces of information.  In the Blogs section you will find technical articles focused around .NET Development, mostly C# content articles and with an emphasis on ASP.NET and DotNetNuke implementations.  If you are looking for technical assistance the Forums section is a great location to ask for specific help, I try to respond to all forum postings as quickly as possible.

For those looking to interact with me in a more direct route, such as Consulting or for a Speaking Engagement, these sections of the site will provide you the needed information to get in contact with me.  If you are looking for more information on my career and experience you may review an online copy of my Resume, or Contact me for more information.

Lastly for those attending any classes that I teach for the Business Information Systems department of Des Moines Area Community College (DMACC) you can view the Courses section to download any course specific documents.
