Princeton Builders, the construction division of The Princeton Companies, has a proud history dating back to 1983 in Leesburg, Virginia. Founded as Ballinger-LaRock by two visionary architects and close friends, the company has steadily grown in stature and expertise, expanding its range of capabilities and taking on increasingly complex projects.

The Princeton Companies has been a trusted leader in commercial design-build services for over 40 years. Although our roots are in Northern Virginia, our reach extends far beyond. We've successfully delivered construction projects across the East Coast and Mid-Atlantic, impacting national and international landscapes.
