Meet the family behind the enclosures at www.polycase.com. Pictured on our shop floor in Avon, Ohio is Steve Began, alongside his three daughters Erica Chiricosta, Kate Began, Jessica Began, and son-in-law Jeff Lehnerer, who now handle the day-to-day operations.

We actually have several families working side-by-side at Polycase. It’s grown into a place where multiple generations and households choose to work together under the same roof. From parents and children to siblings and spouses, our team treats one another, and every customer like family.

In an industry full of automated response loops and overseas distribution hubs, we do things differently. When you call Polycase, you aren’t routed to a call center miles away. Instead you get a direct line to people who know our products inside and out, value your time so they ensure your order ships out the same day.

Real American manufacturing. Real people standing behind every box.
