About QLS

QLS was formed in 2004 by Leo Modicamore and Jeff Glowacki. With extensive backgrounds in trucking and automotive, Leo and Jeff saw the need to perform proactive quality services for suppliers in OEM plants. With clear benefits for both suppliers and OEMs, QLS has expanded across North America. Today we’re proud to say we’ve helped thousands of quality professionals improve product quality.

QLS provides quality assurance and supplier representation services for OEMs and suppliers in a variety of industries. Our focus is to provide top tier service with knowledgeable and responsive personnel.

Meaning of the QLS Logo

The QLS logo shows three links in a chain surrounded by a measurement device. We see ourselves as a strong link between OEMs and their Suppliers forming a supply chain of high quality productivity.

We see our role as serving two customers — The OEM works with us to maintain productivity and improve their Suppliers’ quality ratings over time.  The Suppliers work with us to be their representatives in the OEM plants and to provide instant response to their OEM customers. This is a win win situation and value added for both parties.
