Pittsburgh is the hub of southwest corner of Pennsylvania. But the city of Pittsburgh is part of Allegheny County, which features a number of other large and mid-sized towns. Around the region other large towns include Greensburg, Washington, Beaver, Uniontown, and Somerset.
Just as Pittsburgh is the population center of southwest Pennsylvania, it is also the healthcare center. It is home to the University of Pittsburgh School Of Medicine. The Pitt-affiliated UPMC health system covers a large portion of the western half of Pennsylvania. Its main competitor in is West Penn-Allegheny, which is owned by Highmark insurance company. Other health systems in the area include Heritage Valley (Beaver), Exela Health (Westmorland County), and Washington Hospital.
