GPJ has a wide variety of clients in various industries: automotive, technology, software, food & beverage, entertainment, including over 40 Fortune 500 Companies.

By 1989, the work that the company had been doing in the west coast had secured as second production facility there, along with moves to seek out clients and opportunities outside the automotive industry, and experimented with developing its consulting capabilities.

This was also brought along with the company winning the account of Chrysler International, leading to the openings of the first European offices in Brussels, Belgium for the firm.

March 1996 saw GPJ's main headquarters and production operation moved to Auburn Hills, Michigan to a larger 300,000-square foot facility.

[1] Creation of high production visual displays for auto shows became a new hallmark for the company, with each custom made and incorporating technologies like simulated-motion and virtual reality.

In the same year, the company also produced the North American International Auto Show (NAIAS) in Detroit with countless of automotive clients utilising rotating turntables, cars, videos, graphics, and other special effects.

In the same year it acquired Conference Planners of Burlingame California, an event management company owned by CEO Chris Meyer.

George P. Johnson played a prominent role in the creation and design of the Lenovo and Bank of China pavilions for the 2008 Beijing Olympic Games.

Lenovo's pavilion in the Olympic green hosted a game to demonstrate Lenovo's active protection systems[4] while The Bank of China's pavilion hosted similar features, having them participate in a virtual stock market game and an interactive sports experience where one can play badminton against a member of China's national team; a Wii-like experience.

Having won a public tender and being selected for designing the Australian pavilion, the company was given $3 million to create an exhibit that represented the culture and diversity of Australia.
