The newly formed executive committee includes Elise Greenberg of Greenberg’s Jewelers and Karen Goracke of Borsheims as vice chairs; Steve Velasquez of Madison Jewelers as treasurer; Tobey Ritchie of Harry Ritchie’s Jewelers as secretary; and Coleman Clark of B.C.

The board of directors plays a pivotal role in guiding Jewelers of America’s strategic vision and industry initiatives. With its refreshed leadership, JA aims to strengthen member engagement, promote responsible business practices, and advocate for the continued growth and innovation of the U.S. jewellery industry.
