our story
ABOUT DIMARCO
A family owned company, DiMarco Construction Co., Inc. was founded in 1980 by Domenic and Phillip DiMarco. Today, the DiMarco Construction project portfolio includes office buildings, restaurants, religious facilities, personnel care facilities, retail stores, and a variety of municipal, industrial, and commercial structures.
DIMARCO CONSTRUCTION HISTORY
DiMarco Construction was founded by father-and-son team Domenic and Phillip DiMarco, beginning as a small masonry and concrete contracting firm built on a reputation for high-quality workmanship. Domenic, a 30-year veteran of the construction industry and highly sought-after brick mason in the Pittsburgh area, laid the foundation for the company’s early success.
In 1986, Phillip earned his Civil Engineering degree from the University of Pittsburgh and became President when DiMarco Construction officially incorporated that same year. Under his leadership, the company evolved from a specialty contractor into a full-service general contractor with substantial in-house capabilities and a fully staffed team of project managers, estimators, superintendents, and skilled field personnel.
Today, DiMarco Construction has successfully delivered commercial, institutional, municipal, and industrial projects throughout the tri-state area. With more than three decades of experience, the company is known for delivering top-quality work on time and on budget—earning long-term client relationships and a reputation built on craftsmanship, accountability, and excellence.
Why DiMarco
A legacy of craftsmanship, integrity, and hands-on leadership since 1980.
DiMarco Construction was founded on a simple belief: do the job right the first time, and the rest takes care of itself.
What began in 1980 with a pickup truck and a wheelbarrow has grown into one of Western Pennsylvania’s most trusted self-performing general contractors - built on reputation, reliability, and results.
