In 1986, Glenn Wadden founded Trihedral with two ambitious goals:

  1. Create the world’s most capable and reliable HMI and SCADA software.
  2. Provide the kind of outstanding support that people don’t think exists any more.

A Permanent Team of HMI SCADA Software Developers

Wadden assembled a team of programmers and engineers with diverse backgrounds in process automation and systems integration and created a flexible work environment to encourage creativity and reward initiative.

Working Hard and Playing Hard

Our corporate culture is to work until the job is done. To retain this kind of skilled and motivated professional, Trihedral offers competitive salaries, benefits, and a stock purchase plan. To reduce stress, Trihedral offices are equipped with games rooms, exercise equipment, and hot and cold beverages. Throughout the year, Trihedral staff enjoy a variety of extracurricular activities such as sports days, Super Bowl parties, and lunch hour barbecues.

A Business Based on Outstanding Support

We believe that personal and accessible technical support is an integral component of great HMI and SCADA software. Supervisory Control and Data Acquisition systems are complex and unique to each customer. Therefore, ensuring system uptime often requires timely answers from SCADA professionals with strong knowledge of the automation industry in general and specific knowledge of each customer’s system and needs.

Our SCADA support offices are side-by-side with those of our development team. This makes it easy to get to the bottom of even the most difficult technical support questions. It also provides developers with direct feedback from customers to help keep VTScada growing with the needs of industry.

With one of our yearly support contracts in place, access to our friendly support team is just a phone call or email away.

Trihedral Engineering Services

Trihedral also provides specialized engineering consulting services in the field of industrial control.
