Paul Rodriguez

Founder & Chairman of the Board

Safety, quality, and integrity are at the heart of NSC’s company values. As Chairman, Paul Rodriguez created the company’s vision and strategic direction, so our practices exemplify these values and support our clients and associates. He works closely with the board of directors and guides the senior leadership team, inspiring a servant leadership culture and results-driven organization.

In his early twenties, Paul moved back into his mother’s house after a business venture went sour. He stayed in a single car garage the family repurposed into a makeshift bedroom and started the staffing company from that garage. Since founding NSC in 2000, Paul has grown the company in staffing services for the marine, skilled trades, light industrial, and technical and professional industries. Through his efforts, NSC has become one of the top 1% of U.S. staffing firms.

Paul is dedicated to providing the best candidate and client experience by honoring commitments and even visiting associates at job sites. He believes in equipping individuals with specialized skills and businesses with quality talent to bring opportunity to workers and communities alike.

“When we equip individuals with specialized skills, we see businesses, workers and communities thrive.”
