DNN Consulting

When we started Efficion in 2004, we did a large scale evaluation of the best CMS / Application Development frameworks available to serve as the basis of the majority of the sites we would build. We chose DNN (aka DotNetNuke). We now use a larger variety of software but we still love DNN. It's well written, has a great community, and it's immensely powerful and endlessly extensible. It is a great base for many types of websites and web applications.

We offer the complete range of services for DotNetNuke:

Efficion has been building DotNetNuke modules since the earliest versions of DNN. We have .Net expertise in both VB.Net, C#, and SQL Server. Contact us to discuss your project and we'll come up with a plan to make it a success.

Efficion provides premier DNN hosting through our top of the line servers in an enterprise-class data center in downtown St. Louis Missouri. Our hosting package include free annual DNN upgrades to ensure your site is always kept up to date and safe. Learn More...

Need someone to just get you started? Efficion can get you running with a DotNetNuke site in a couple days whether on our server, at a another host, or in your own environment. Efficion has done hundreds of DotNetNuke installs in a wide variety of environments. We know how to get it setup right so you can start building out your site right away.

Wondering how to get your DNN site to do what you need it to? Overwhelmed by the thousands of modules available on SnowCovered and the DNN Marketplace? Efficion has worked with hundreds of modules. We can recommend lots of great modules, show you how to use them properly, and keep you away from the modules the lemons. If there's not a module that does what you need.
