🌟 Employee Spotlight: Travis DeBona, Sales Manager 🌟

We’re proud to highlight Travis who’s been part of the Diamond Manufacturing team for over 10 years. Starting as an intern in 2014, Travis has grown through multiple roles to become Sales Manager, working with both our inside and outside sales teams.

In this role, Travis focuses on managing accounts, building strong customer relationships, and finding new business opportunities—all while ensuring our perforated products are delivered safely and on time. He attributes his success to his coworkers at Diamond.
“The group of people around us here are incredible, the industry knowledge is special. Mentorship from Brent and David who are two of the best, always trying to listen and learn from them as much as possible.”

Travis credits the team’s collaboration and friendly competition for keeping things exciting.
“The company culture is something we are really proud of and rightfully so, from sales to purchasing, production, and engineering… we’re lucky that our group communicates very well and works with each other seamlessly. Our sales team always has each other’s backs and know they can count on one another.”

Looking ahead, Travis is inspired by the opportunities that come from being part of Reliance Inc.
“Our parent company Reliance Inc. is such an impressive group we are really lucky to be a part of; it challenges us every day to continue to grow and improve. “

From Dallas, PA, Travis enjoys the local pizza scene and spending time with his wife and two rescue dogs, Wade and Dobby.

Thank you, Travis for your leadership, dedication, and commitment to the Diamond team.

Diamond Manufacturing Company was once again honored to be part of the 9/11 National Day of Service by rolling up our sleeves, throwing on our hairnets and giving back. 💙
From Philadelphia to Nashville, our teams came together to pack meals, lend helping hands, and show what community, compassion, and action look like in practice. Together, we made a real impact—and every box packed was a reminder that service unites us.
We’re proud of the difference our people made. Here’s a look at some of the moments from this year’s event ⬇️

Today, we remember 9/11—a day that changed our nation. But it’s also a story of community, compassion, and action. Last year, on 9/11 National Day of Service, our Reliance Inc., FOCs came together to make a tangible difference—packing meals, lending hands, and spreading hope.

Come back tomorrow to see the moments from this year's event. We can't wait to share.
