Construction has begun on a $1 billion expansion of Hoag Hospital in Irvine, which will add two hospitals specializing in women’s health, digestive illnesses, and cancer.

“Having a hospital provide services for complex issues, here locally, is beneficial for everyone,” Irvine Mayor Farrah Khan told The Epoch Times.

The new facilities will be named the Sun Family Campus in honor of philanthropists Diana and David Sun, who donated $50 million to the hospital in March after Diana’s 95-year-old mother underwent successful brain surgery at Hoag’s Pickup Family Neurosciences Institute.

“When we get to some of these clinical spaces, it’ll literally change healthcare for the greater Irvine community in a very meaningful way,” Hoag CEO Robert Braithwaite said in a press release.
