Description

Descriptor Systems was founded in 1984 by Joel Barnum and Tom Gaven (who has since moved on to to other things). Since then, we have been in the technical training business, providing courseware and training services to companies across the United States, Canada, Europe and Asia. We specialize in programming languages and related technologies, such as Java, C++ and XML.

Joel Barnum has been a top-notch instructor for over 25 years and consistently receives outstanding evaluations. Couple that with our unconditional money-back guarantee and our high-quality courseware, and you can't go wrong.

You give us a specification, and we will give you a custom course, complete with presentation materials in PowerPoint or Adobe PDF and hands-on lab exercises. We specialize in programming courseware including Java, XML, Web Services and .NET, but if you need any other technical courseware, drop us a line!
