About Nexus Engineering Group

At Nexus, we think differently. We feel that engineering firms shouldn’t focus on maximizing hours, or be the task-oriented businesses of the past. An engineering firm should be easy to work with and share the same passion and drive for project goals as the client. Engineers should be aligned and engaged with the client from the very start, which is critical to the success of complex projects.

Nexus is not your typical engineering firm. Our professionals bring decades of experience, skill, and expertise to every project. Teams of creative and talented professionals focus on customers’ goals as if they were their own. No one else brings the passion and moxie to the table to tackle challenging projects like the people at Nexus do.

If you are looking for an engineering firm that thinks differently, performs better, and has your best interest at heart, look to Nexus. Not only will our teams get the job done right, we think you will genuinely like working with us, too.
