For the first time in its more than 100-year history, the Greenville Health System won’t have Greenville in its name.

Starting next year, GHS and Midlands-based Palmetto Health will officially retire their names and start going by Prisma Health, which is the largest hospital system in South Carolina and top 50 in the United States.

GHS and Palmetto Health leaders made the announcement Tuesday morning at campuses in Greenville and Columbia.

The two hospital systems, which have 14 hospitals and more than 1 million patients, announced the merger last year and made it official in November 2017. The systems estimated between $80 million and $100 million in savings from refinancing debt with the merger.

At the time, the two systems kept their names but operated under an interim parent company, SC Health Company.

Todd Miller, senior vice president of marketing and communications with Prisma Health, said the new name “is an acknowledgement that we need to be singular, and we need to be unified, and we want to express that through using a brand that can be the same in whatever location that we’re in.”

Prisma Health was selected from among 1,000 names, Miller said.

“We brought in team members, leaders, physicians, (and) community members to help us in evaluating name options to ultimately determine what name felt right, looked right, sounded right, and most importantly, what name could we own?” Miller said.

Miller said the organization hopes to give its own meaning to the unofficial word “Prisma,” stemming from “prism.”

“Prisms are colorful, and they’re bright, and they’re light, and they’re multifaceted. That word has such positive connotations to the people we shared it with, and they saw possibilities because it can represent the diversity of our people, the diversity of the people we serve, the multifaceted nature of our business,” Miller said. “It just felt like it had a lot of possibility, and so that was how we chose the word, then we designed a logo to go with it.”

GHS President Spence Taylor said it will take some time to rebrand everything, and the agency doesn’t have an official budget yet on how much that will cost.

“The capital dollars we pay for signage each year is not insignificant,” Taylor said. “I don’t care if it’s the GHS old logo or the new Prisma logo, you’re just adding something. I think it’s real important that we do it responsibly.”

The names and brands of individual hospitals under Prisma Health won’t change.
