Why choose TPG Engineers
<span style="font-weight: bold;">Hands-on Experience</span>
Hands-on Experience
We have spent time in the field commissioning and troubleshooting process units.  This gives us insights and expertise well beyond simply working from behind a desk.  When needed we will go above and beyond to ensure the intangibles of the design are considered, such as interviewing Operators and Maintenance to understand where previous iterations of the design may have fallen short.
<span style="font-weight: bold;">A True Passion for Engineering</span>
A True Passion for Engineering
We work because we love engineering and the impact we have on our industries.  We know what we do today may set the standard decades beyond the completion of the design process.  We approach this responsibility with passion and integrity, excited by new project challenges but mindful of the risks associated with every decision we make. Whether small or large, we strive to act ethically to deliver the best results and work with our Clients to make sure their needs are met.
<span style="font-weight: bold;">Technical Aptitude</span>
Technical Aptitude
We understand the digital era is upon us, and has been for some time.  For process engineers, this means leveraging the AspenTech suite of softwares, AFT Fathom and Arrow, AutoCAD, Bluebeam, Excel, and other electronic tools to work more efficiently than ever before.  However, we also understand that simply being able to use the tools isn't good enough.  Firm understanding of engineering design pricipals can be the critical difference between a design that fails and one that thrives.
