Katie’s involvement with our employees allows her to make changes that are crucial for not only our team but our customers and vendors.”

“Some of the largest, most successful businesses in the world are family-owned. I believe that is not a coincidence,” Poehling Seymour says. “The magic of the passion for something at the onset, an entrepreneurial trait that never quite diminishes with the passing of generations, an ingrained knowledge for an industry, and a culture that is inherently familial comes together for companies and families that can harness it in ways that can’t be replicated otherwise.
“I truly believe I am a steward charged with the care of the asset and legacy that has been entrusted to me in the form of this business. It is an honor to stand on the shoulders of those that came before me to build something that will benefit a future I cannot yet see ahead of me.”
