Providence Little Company of Mary Medical Center in Torrance has received a $20 million donation from philanthropists Priscilla Hunt and the late Donald G. Hunt, the hospital said Thursday.

It is the largest donation ever given to the Catholic not-for-profit hospital and will be used to support Little Company of Mary’s Cardiovascular Center of Excellence Campaign, according to a press release.

“This extraordinary gift to Providence Little Company of Mary is an inspiring demonstration of how donors throughout the years have transformed this hospital through their generosity,” Sean Armstrong, the hospital’s chairman, said in a statement. “The Hunts believe that everyone in our community deserves access to the highest quality health care, and this generous gift ensures that South Bay residents will continue to receive world-class cardiovascular care right here in the community.”

The Cardiovascular Center of Excellence Campaign is investing in a $35 million renovation and new patient care rooms. The hospital’s Heritage Tower will be renamed the Donald & Priscilla Hunt Tower as a result of the gift, Little Company of Mary said.

The couple has donated to hospitals in the past, including a $13.5 million donation to Torrance Memorial Medical Center in 2011.

Little Company of Mary was No. 20 this year on the Business Journal’s list of hospitals in L.A. County, which were ranked by 2016 net patient revenue. The hospital reported $413 million in net patient revenue and $1.9 billion in gross patient revenue last year.
