We build relationships and support projects by providing staffing and advisory services.


The Premier Resources Group (PRG) began providing staffing and advisory services to the engineering and construction industries in 2008. What started as a side project of supplying a few contract resources to a large owner company quickly grew into an award-winning staffing and advisory services company that supports clients worldwide. After being listed twice on the Inc. 5000 list of fastest growing private companies in America, and because of its developing reputation within the industry, the Premier Resources Group (PRG) recognized that it was uniquely positioned to provide not one, but multiple services: to recruit and deploy high-end advisors to support clients’ projects and initiatives; as well as provide traditional project staffing services. The combination of industry experts and project staffing services allows the Premier Resources Group (PRG) to serve as a one-stop-solution for staffing and advisory services to help take your organization to the next level.
