Conewago Contractors, Inc. is a family owned and operated real estate development and investment company, founded by Donald B. Smith Sr. in 1956 and incorporated in 1963. The business started with a sole focus on general contracting, specializing in public works projects. Conewago ventured into real estate in 1981, when a customer transferred ownership of an in-progress project in lieu of payment for work performed. The following twelve years saw the company operate as a dual-mandate contracting and development company until the general contracting division was spun-off in 1993 as Conewago Enterprises, Inc.   

From 1993 onward, Conewago has operated exclusively as a real estate development and investment company. At Donald B. Smith Sr.’s direction, the company developed residential communities, office buildings, community shopping centers and industrial parks, continuing to work closely with Conewago Enterprises on these projects throughout Pennsylvania and northern Maryland.

In 2004, leadership was assumed by Donald Sr.’s son, Allen M. Smith. Under Allen’s guidance the company shifted away from residential product and focused on commercial, office and industrial projects. Diversification among these asset classes provided steady growth to a portfolio culminating in three shopping centers, medical and professional office buildings, flex industrial buildings and warehouses. 2019 saw the beginning of the company’s third strategic shift, as over a four-year period, Conewago disposed of its shopping centers and the majority of its office product. Today, with the exception of one medical center, the company operates exclusively in the industrial domain.
