Our Locations

In 1890, 29-year old Herman F. Wohlsen started Wohlsen Construction Company in Lancaster, PA. Some 130+ years later, our company is firmly established throughout the Mid-Atlantic and Northeast Regions. The legacy that Mr. Wohlsen left behind, one of superior quality and service, remains as strong today as it was decades ago. Wohlsen currently maintains offices in PA, DE, MD, VA, NJ, and CT. We are also active members in eight regional chapters of Associated Builders & Contractors. Our experience spans over a dozen unique markets, and we have great relationships with the best subcontractors in the regions served.
