Development Company


Mosites Development Company was established in 1969 by Donald A. Mosites and Steven T. Mosites, both graduates of the University of Pittsburgh, to develop and manage real estate for itself and others.

The Development Company has a very diversified real estate portfolio of over two million square feet of buildings including, but not limited to, office buildings, national restaurant chain leases, retail shopping centers and light industrial and warehouse buildings.  Also, Mosites controls over 600 acres of land for light industrial parks, office and research parks, individual buildings and future sites in Pennsylvania, West Virginia and Florida.

Mosites Development Company has such prominent clients as Westinghouse, Bayer Corporation, Nabisco, Kmart and Wal-Mart as well as other national and regional companies.  Mosites will develop, construct, value engineer, consult, lease, build-to-suit and manage properties for the most efficient and productive benefit of our clients.

Mosites Development Company will, in the future, develop and manage properties as the demand and opportunities in the Western Pennsylvania region continue to present themselves.
