Careers at GPI

From a two-person firm in 1966 to over 1700 employees, GPI has grown and thrived because of our focus on what makes us unique: our people. As an employee-owned firm, we know that our people are the foundation of everything we accomplish. That’s why our number one strategic objective is employee satisfaction. 


From interns to senior leadership, GPI invests in our people. Our core values, exemplified in our 7 Strategic Objectives, encompass this belief, and create a culture of excellence, striving to showcase the talents of each employee and offer our staff the ability to fully develop their skills to their fullest potential. As an employee-owned company, GPI is uniquely positioned, evoking every employee’s entrepreneurial spirit, which collectively distinguishes us as a best-in-class firm.


In our Intern Program, you will be part of a team that creates the infrastructure that people need most. Our interns are involved with everything from project work to networking events and exposure to leadership and mentors. The intern experience goes beyond your assigned job.
