Jeff Greenwalt’s path into industrial development began in Greenfield, Indiana, working alongside his family in a general contracting business where the fundamentals of construction weren’t just taught, they were lived. That foundation proved to be everything. Over the next several decades, Jeff scaled that family operation into a national development and construction firm, earning a place among the top 100 construction companies in the United States and building a reputation for tackling projects that demanded more than the average developer could offer.

But Jeff’s ambitions didn’t stop at the domestic market. He took his expertise overseas, where he developed off-grid energy solutions in environments that required creative problem-solving, resourcefulness, and the ability to execute without the infrastructure most developers rely on. It was the kind of experience that sharpens a skillset most people in this industry will never develop and it fundamentally shaped the way Prime Stone Group approaches every project today.

When Jeff returned stateside, he brought that global perspective back to industrial real estate development and the results spoke for themselves. In just six years, he built and led a Midwestern-based industrial platform that delivered over 50 million square feet of development, with another 20 million square feet in the pipeline for future development. That is not a number that happens by accident. It is the product of four decades of hard-won experience, an operator’s instinct for execution, and a standard of excellence that has never wavered.

Prime Stone Group exists because of that journey and because clients with complex, high-stakes projects deserve a partner who has already solved the hardest problems in this industry.
