Our Vision

Efficion Consulting was created with the goal of employing great open-source solutions to help companies optimize their efficiency, communication, and effectiveness and ultimately increase their revenue and profitability. Through the use of established open source software, Efficion can help you optimize your business.

In creating Efficion, we were looking to solve a problem. Namely, Custom software development is slow and expensive. With Efficion, we're moving away from custom software and instead, starting with solutions that meet 80% of client needs without requiring custom programming. For the final 20% we do a mix of custom development and integrating 3rd party solutions to create the perfect solution.

Utilizing existing building blocks in the creation of websites, intranets, and extranets allows us to greatly improve quality, time-to-market, reliabilility, and cost .

Efficion may not have the right solution for you, and if that is the case we will tell you so upfront. We truly believe that with the software library we have in place, we can meet the needs of many companies and organizations, at a greatly reduced cost and superior product to most other web development firms.

Contact us and give us a chance to show you how we can help you improve your business.

Our Solutions

Many of our solutions are built on top of an Open Source, ASP.NET-based Content Management System called DNN. DNN allows for the rapid development of web sites that are powerful, flexible, attractive, and easy to maintain; even for people that don't know HTML.

DNN sites are created by adding pages and then adding modules to each page. Modules include things like a contact list, an event calendar/list, Announcements, surveys, a data table, ... The base portal has 25 different modules built into it and a extension structure that makes it easy for developers to create new modules or modify existing modules to meet specific needs. This makes it easy for non-technical people to add content to their own site or page.

DNN includes a Rich Text Editor that looks and works much like MS Word and makes it easy to create attractive content that can include pictures, links, styles, headings, and more.

Contact us today so that we can show you how fast we can build you a great, functional website that will wow your clients, partners, or members.


Anyone can build a website, but building a great website that truly reflects your organization is a challenging and involved process. At Efficion Consulting, we are able to offer a variety of services to ensure that you get the best possible solution. Learn More...
