Future podcasts will feature leaders from retail chains, independent jewelers and online retailers as well as manufacturers, wholesalers, and media and marketing executives.


“We’ve gotten tremendous response from our Monday emails that began several months ago, initially conceived as a result of the COVID crisis,” COO Angelo Palmieri said. “The next logical progression was a podcast.”

“It was obvious in the unprecedented times we’re experiencing, no one individual or company has all the answers. In trying to figure out how to navigate these challenging times, GCAL will be reaching out so our industry can experience the power of sharing information. And we are honored to have Harold Dupuy and Carl Lehnhardt of Stuller for our premier broadcast interview.”
