Steve Yeko, Sr., started in the jewelry business in 1974 by answering a help wanted ad in the local Milwaukee newspaper. Steve started as a Salesperson for that company. Within 12 months, he was promoted to Store Manager and helped open a new location for the jeweler in Illinois. Two years later, Steve was again promoted to the District Manager of five jewelry store locations in Illinois and Wisconsin. In 1982, Steve and Heidi Yeko branched out and started their own business in Antioch, Illinois.

In 1992, Steve Yeko, Jr., came to work for The Diamond Center as a Salesperson. After three years of sales experience, Steve Jr. was promoted to Sales Management.
