The Gatorade Sports Science Institute, often featured in the company's commercials, is located in Barrington just west of downtown, across the street from Barrington High School. Barrington was also formerly home to GE Healthcare IT prior to relocating to Chicago in 2016. Other notable businesses include defense contractor ISR Systems, part of the Goodrich Corporation (formerly known as Recon Optical), and commercial real estate developer GK Development. For many years, the village was home to the Jewel Tea Company; its former headquarters was razed in the early 21st century for redevelopment as Citizens Park.
