Company Overview/History
Founded in 1985, Pronesti Companies began with a single tractor and dump truck under the vision and leadership of its executive founder. What started as a modest operation grew into a full-service excavation company recognized for its expertise in golf course construction, custom home sites, small subdivisions, and commercial site development. Over the decades, the company expanded into a fleet of more than 40 units, enabling it to tackle projects of varying scale with efficiency and precision. This growth reflects not only investment in equipment but also a commitment to building lasting relationships with clients, agencies, and employees. In 2012, Pronesti Companies further strengthened its capabilities by acquiring Pronesti Environmental, retaining its experienced workforce, and expanding services to include full-service erosion control and weed abatement. This strategic expansion allowed the company to deliver comprehensive solutions that balance construction excellence with environmental responsibility. As Pronesti shrinks its excavation footprint, it has focused on growing its environmental side into what it is today. Despite significant growth, Pronesti Companies remains firmly rooted in the leadership that founded the company in 1985. Under the same experienced guidance and long-standing vision, the company continues to deliver reliability, quality craftsmanship, and pride in every project.
