The culture we've established at Connor & Gallagher OneSource has played a direct role in the growth of our company and is a big reason why we have one of the lowest turnover rates in the industry.

In August of 2015, we moved into a brand new, state of the art office overlooking I-88 in Lisle, IL. Everything that went into the construction and design of our office was meant to augment the culture we've established at Connor & Gallagher OneSource. Our glass offices and open floor layout facilitates communication and a team working environment, common space provides a place for employees to collaborate with one another and be creative, and our cafe style lounge provides a space for employees to relax and converse with one another and build camaraderie.
