Reliable Engineering Since 2016

Lead Engineer Paxton Rothwell (Oregon License 97490PE) worked at large and small engineering firms since 2016. He oversaw projects ranging from a small roof repair after a fire to residential additions to ground up ADUs and commercial buildings. Paxton’s attention to detail, engineering knowledge, and gentle client relations makes him stand out in the field.

In early 2024, Grand Engineers formed with the vision of providing accessible and affordable in person engineering services to the greater Central Oregon region. We are happy to take on any project in Oregon State virtually.
