Meet Derek!

Derek joined the Derryberry’s family in 2022 and has been taking great care of our customers ever since. When the workday ends, he’s spending time with the people who matter most—his wife and child.

We’re also proud to call him a veteran and appreciate the service and dedication he has shown to our country. We’re lucky to have Derek on our team! 🇺🇸

This semester, our state-registered apprenticeship program dove into the details of airflow and duct design. It was a challenging course, but our apprentices rose to the occasion and earned a 100% pass rate!

We’re so proud of their hard work and commitment to always learning more about the trade. 👏🏼🔧

Meet Brandon!

He started at Derryberry’s as a technician back in 2007, and today, he leads our company as CEO. Outside of work, you’ll probably find him fishing at his pond, spending time with his wife Ashley and their dog Raynee, or lending a helping hand to a neighbor or friend — because that’s just who he is.

We’re incredibly grateful to be led by someone so intentional, hardworking, and kindhearted. Brandon truly leads by example, and we’re lucky to have him at the helm of Derryberry’s!

Meet Justin! 👈🏼

Justin joined our team in early 2025 and has already grown into a fantastic maintenance and service technician. He’s picked things up quickly and continues to impress us every day with his hard work and positive attitude.

Outside of work, Justin is a first-time dad who loves spending time with his daughter, wife, his cat Mia, and dog Jack. If you follow along on our social media, chances are you’ve already seen a glimpse of his hidden acting talents too. 😂
