For Shamus O'Shea, the founder of O'Shea Equipment Co., heavy machinery is more than a business: It's a lifelong passion.
Growing up in Texas, O'Shea spent his early years on job sites, introduced to the world of construction equipment by his father, a logistics professional. This early exposure to "yellow iron" sparked a fascination that would eventually lead him from playing with Tonka toys to founding a specialized excavation equipment company.
"I've always had a knack for equipment," O'Shea said. "As a kid, I'd be on job sites with my dad, and I fell in love with the machines. I knew this was what I wanted to do."
After earning an advertising degree from Texas State University and starting a career in equipment finance, his career path took a turn when he encountered an amphibious excavator for the first time.

"It was unlike anything I'd seen before," O'Shea said. "I knew right then that I wanted to bring this level of specialty equipment to contractors who needed it."
In 2021, he launched O'Shea Equipment in Houston, diving into the world of amphibious and long-reach excavators with a commitment to high standards and a hands-on approach to service. The company operates in a specialized and technically demanding space, supplying machines built specifically for marshlands, wetlands and other challenging environments.
"Our machines aren't just your standard equipment," O'Shea said. "We engineer and assemble these machines for stability and precision. They're most effective in 6 feet or less of water, where they can push off or travel on the bottom surface. That stability is what keeps operators safe and allows them to work efficiently."
Safety is one of O'Shea's top priorities, and his dedication to quality control ensures that every machine in the fleet meets rigorous standards.
"I'd rather have 10 machines that I know are solid than 50 that aren't," he said. "The most important part of this work is that my operators go home safely every night."
To support that goal, he oversees customization personally, outfitting machines with features like skeleton buckets that drain water and chains that break up stubborn loads. Stronger hardware and additional frame support.
"These little technical details make all the difference," O'Shea said. "In wet environments, water weighs down a bucket, so we drill holes to let it drain. It keeps the machine working faster, longer and saves fuel."
O'Shea Equipment's commitment to quality goes hand in hand with O'Shea's hands-on approach to customer service.
"When a customer calls, they're talking to me," he said. "I'm the owner, and I know every machine inside and out. Here, you get help right away."
This earned O'Shea a reputation for responsiveness and reliability and sets the company apart from the field.
Looking back on his journey, O'Shea said, "I've put everything I have into this company — my heart, my knowledge, my passion. I started with one machine, and now I have a fleet, all because I wanted to give contractors equipment they can rely on."
Today, with a growing fleet and trusted partnerships, O'Shea is focused on expanding while maintaining his commitment to quality and safety.
"The goal is to grow but to do it the right way," he said. "I want every contractor using O'Shea Equipment Co. to know they've got the best tools for the job."
