SQN was named after the latin phrase "sine qua non" when literally translated means, "without which not." The dictionary meaning of this phrase is "absolutely indispensable or essential" - this is the fundamental concept on which SQN was founded. We believe it is of utmost importance to hire talented and dynamic professionals. By nurturing their growth with an emphasis on teamwork, objectivity, and continual training, we aim to sustain qualified professionals who are prepared to deliver and ensure your project’s success. At SQN, we emphasize a culture driven by excellence and hold ourselves accountable through each step of the way.
SQN is certified as a Disadvantaged Business Enterprise (DBE) by the Chicago Transportation Authority, Illinois Unified Certification Program (IL UCP), and as a Women’s Business Enterprise (WBE) and Minority Business Enterprise (MBE) by the City of Chicago.
