Across the country and across generations, Primus delivers solutions that power businesses, government, education, and research, connecting individuals and entire communities. Primus is your single-source expert in the planning, design, and construction of high-performing, cost-efficient communication solutions.
In 1980, Dr. Michael Greenwald and Robert Cramner started Primus as a telecommunications company serving the needs of the land mobile radio market with quality products and unprecedented customer service. Seeing our long-term potential, Dr. Greenwald purchased the business in 1991 and promoted Mr. Michael Johnson to President.
Over the years, Primus' presence in wireless communications grew exponentially by broadening our capabilities and national footprint, and helping customers construct and maintain some of the largest communication networks in the world.
In 2013, under the new ownership of Eric Greenwald and continued direction of President Michael Johnson, Primus entered a new dynamic growth phase with a significant expansion of our corporate headquarters in Morris Illinois.
With our unparalleled expertise and service standards still practiced today, Primus continues building connectivity for generations to enjoy and trust.
Our high customer service standards and unwavering commitment to excellence has built our strong reputation as the industry partner you can rely on.
