About DUNN Training

Dunn Training was an Atlanta, Georgia based company made up of dedicated technical trainers and mentors with extensive experience in multiple industries with Microsoft technologies.  Our primary focus areas were technical training on the Microsoft .Net platform, Client Development with popular Javascript libraries, Database Development and Administration with SQL Server, Oracle and MySQL.  

The company was founded in 2002 and enjoyed steady growth until 2020 when founder and CEO, Mark Dunn, was diagnosed with cancer. His three year battle ended in remission but also in the shutdown of the company.

Today, Mark can be found enjoying his retirement on the shores of Lake Lanier. He is still available to teach an online class once in a while. Just use the contact page if you are interested in hiring Mark to teach C#, MVC, SQL Server for Developers, Reporting Services, or Javascript and HTML.
