Our History

/ About / Our History

Our story begins in 1861 when a young man named Henson Robinson founded a business he dedicated the rest of his life to build. Henson Robinson Company has had a front row seat to many historical moments such as the presidency of Abraham Lincoln and the invention of air conditioning and first condensed gas furnace by Carrier. In fact, Henson Robinson even supplied Union Soldiers with tin ware during the Civil War which led to the company quickly becoming an industry leader.

This success carried many decades later to March 1997 when Henson Robinson Company became an employee-owned business. One location change to Great Northern Avenue and many awards later, Henson Robinson Company acquired Petersburg Plumbing and Excavating LLC in 2011 to keep up with demands of today’s marketplace.

In the 160+ years of Henson Robinson Company, there has been one thing that has remained the same: the importance of customer service.

From the beginning, Henson Robinson Company had the goal of making customers top priority, no matter how big or small their purchase. Charles Robinson often could be heard telling employees:

“Our customer’s problems are our problems, so try to solve them as best you can.”

This dedication has built an excellent reputation for quality service in the Central Illinois area. We are proud be leaders in the industry and look forward to growing for many years to come.

160 years ago a young man named Henson Robinson founded a business which he gave his name, and then labored the rest of his life to build. That time and energy were well spent; the company he founded during Abraham Lincoln's term as president is still prospering today. From the beginning, the Henson Robinson company held the idea that all customers should be treated with respect, no matter how small or how large their purchase. Charles Robinson often told his employees, "Our customer’s problems are our problems, so try to solve them as best you can."
