Where Expertise Meets Execution
With deep roots in the Western United States, we understand regional operating environments and rigorous compliance requirements, applying a broad range of technical expertise to deliver reliable, well executed system integration solutions.
Our Process
Future success starts with today’s specifications
While modernizing existing operations or creating an entirely new control or automation solution seems overwhelming, we start by understanding what you have in place and outlining your long-term goals for your system. Moving through the design and build phases with transparent communication keeps stakeholders informed and builds the long-term partnerships clients value.
Regional Knowledge, Real Support
System design and support shaped by regional operating and regulatory realities.
Western U.S. industrial facilities operate under some of the nation’s most stringent environmental and air-quality regulations, requiring careful attention to monitoring, reporting, and emissions control. Industries like mining, energy, and manufacturing must navigate complex permitting, dust management, and state oversight that directly impact system design and operation. With deep regional experience, GTH designs and supports automation systems that align with these regulatory realities while delivering reliable, safe, and long-term performance.
A Legacy Built on Service
For nearly a century, GTH has lived the legacy of "The House that Service Built"
We foster a culture of continuous improvement, technical excellence, and customer-focused support that earns trust long after a project is complete. That commitment to service continues to guide how we approach every project—combining deep technical expertise with a focus on long-term customer success. From initial design through ongoing support, we build solutions that perform reliably and evolve with our customers’ needs.
