St. Clair Health on May 6 unveiled the centerpiece of the largest expansion in its nearly 70-year history — the $125 million, state-of-the-art Dunlap Family Outpatient Center.

 The 280,000-square-foot center, in development for several years, will bring under one roof the outpatient services of the South Hills health system. It began with a gift from the Dunlap family, whose patriarch, Ed Dunlap, is the founder of Centimark.
