Extensive knowledge of custom web and software solutions for businesses and manufacturing processes. They also develop sports apps. It was fun working with them on marketing the Tucson Tech Talks event. They had the website up in a week! Can’t be beat on their internal communication strategies and password security information.

Heidi and House Trevethan excel at customization. How many companies try to sell computer programs to operate your business? How many are a perfect fit? All of them have something they don’t do, leaving you with frustrating tech-gaps. At House Trevethan they build computer programs to run and promote your company. Everything they do is about customizing your technology for your exact specialty, exact needs and exact goals. Don’t waste your resources on technology that doesn’t fit. Get a custom product designed just for your business. You can also receive service on that product that will develop, grow and change as you do. Shannon Kaye Germanos
