Driving growth from the ground up
Family-owned PMI powers aggregate industry and local economy
TO BUILD ROADS, bridges and foundations, you first need rock-solid infrastructure—literally. For more than four decades, Process Machinery Inc. in Shelbyville has helped make that possible.
Founded in 1979 by David Miles and his father, William, PMI designs and builds full-scale plants that process stone, sand and gravel for the aggregate industry. Today, under third-generation leadership of siblings Daniel Miles and Jennifer Miles Ratterman, PMI’s 120 employees supply and service quarry operations across the country.
“We’re not just a supplier—we’re a partner to our customers,” says Ratterman, PMI’s executive vice president. “We offer complete solutions—from engineering and fabrication to on-site installation.”
Though the company has grown steadily for years, it’s never outgrown its roots.
“Working in a family-owned company has been personally rewarding,” Ratterman says. “Daniel and I have worked in various roles throughout the company, and that experience helps us stay grounded and connected to every part of our business.”
That connection extends to the community. When PMI needed to expand, they stayed in Shelby County—a decision Ratterman calls “deliberate and meaningful.”
“This community has supported us for nearly 30 years,” she says. “By growing here, we’re creating local jobs, working with local vendors and investing in the future of our hometown.”
PMI’s commitment to community also includes partnerships with local schools and nonprofits, and a collaborative relationship with Shelby Energy Cooperative.
“Shelby Energy has been an outstanding partner,” Ratterman notes. “From energy audits to assistance with tax credits, they’ve been proactive in helping us move forward.”
“PMI represents the best of what it means to do business in a cooperative-served community,” says Mary Beth Dennis, director of communications and member services at Shelby Energy.
“Working for a third generation owned and operated company means you’re not just part of a business, you’re part of a legacy,” adds Jackie Disponette, manager of marketing and employee relations. “There’s a deep-rooted pride in everything we do at PMI, and it shows in the way we treat our employees, our customers and our community. You feel the commitment to quality, to people and to doing things the right way. It’s rock solid.”
