About
our company
Gentry Civil Corp (GCC) is the Idaho expansion of G.J. Gentry General Engineering, Inc. (GJG), now proudly serving the Boise area and beyond. With over a decade of proven experience, GJG has specialized in underground utilities (waterline, sewer, and storm drain), grading and excavation, and concrete flatwork across commercial, industrial, and residential sectors. The company has built a strong reputation in Southern California as one of the region’s top general engineering contractors. Now, with the rapid growth across Southern Idaho, GCC is proud to bring that same standard of excellence to a new frontier.
As a full-service general contractor, GCC is uniquely positioned to self-perform core scopes of work across public works and heavy civil construction. From initial earthwork and utility trenching to site concrete and paving, our in-house crews bring consistency, control, and craftsmanship to every phase of a project. This hands-on approach minimizes delays, ensures accountability, and delivers better results—from the ground up.
At GCC, being the best goes beyond the job site. Founder Garrett Gentry believes that every employee should be treated like family. When people feel valued and know their work matters, they go above and beyond. GCC was built on the belief that companies should focus on the men and women who dedicate their lives to the work—not just corporate strategy. Providing opportunity and stable careers for generations to come is at the core of everything we do.
Our continued growth is driven by great customer service, reliable human resources, a deep commitment to safety, and competitive pricing. With a 100% client retention rate, many of our customers have partnered with us since day one.
Safety is our top priority. We believe our employees are our greatest asset, and their well-being comes first. That commitment extends to our customers and the communities where we operate. Our dedicated safety department oversees every project to ensure every worker returns home safely—every single day.
GCC services all of Idaho. No job is too big. With the equipment, manpower, and experience to handle any project—and more than 300 pieces of machinery ready to deploy—you can count on GCC to get the job done right.
