Madison Sales Group has been in business for over 70 years, and George Denenberg was there from the beginning. This started the family tradition. In 1946, Madison Sales Group was opened at 22 West Madison Street in Chicago’s business district called “The Loop.” Madison Sales Group later moved to 29 East Madison Street right in the heart of Chicago’s historic Jeweler’s Row (Madison Street & Wabash Avenue). Madison Sales Group sells high quality products at wholesale prices. They also specialize in custom designed jewelry. 

Then in 1985, Madison Sales Group moved to Northbrook, where it is still today. George’s son, Marc, joined his father in the business in 1982. Prior to joining his father in the business, Marc became a certified gemologist at Gemological Institute of America (GIA) in California. Due to their customer’s request, Madison Sales Group also expanded into a second business that focuses on Brand Marketing and Custom Promotional items. Marc spearheaded the Promotional Products even further when he joined the business and now Madison Sales Group has customers all over the world. These items are personalized for any particular business. Madison Sales Group is able to create tools that connect your audience with unique and customized items to boost brand recognition. Our global sourcing capabilities allow our clients receive the best pricing possible. We have tenured employees oversees to ensure that our high quality standards are achieved for our clients.

Both aspects of Madison Sales Group provide high quality products for great prices. Quality customer service is what the business has been built on for the past 7 decades years! Marc’s son, Adam, has also joined the family business and wants help keep this a real family tradition!!
