JACKSONVILLE, Fla. -- The staff on the third floor of Mayo Clinic's north wing handle oncology, and bone marrow transplants, among other things.

The nurses there simply refer to themselves as Three North.

"On Three North we are really close," said 29-year-old Nicole Barlanti.

"I mean, we have arguments and stuff, but we are so close," she said laughing.

Barlanti has been a nurse at Mayo since 2007. But the mother of two, a five-year-old daughter and 8-month-old son, hasn't been able to be with her Three North family in months.

"I want to be there working," she said from her Orange Park home. "I really love my job, but I can't right now."

In January, right after her son was born, she started feeling sick.

"It was nausea, headaches, I was in a lot of pain," she remembered.

At first, she said her doctors told her it was related to postpartum issues.

"But I eventually got so sick, I told my mother-in-law to take me to the hospital."

At the hospital doctors did a brain scan.

They found a massive brain tumor.

"I have glioblastoma stage 4," she said. "It's a very fast growing tumor."

Devastating news for the young mother, and her family -- both at home and at Three North.

"We work in oncology so we see this everyday," said co-worker and Three North nurse Amanda Pendleton. "But to have it happen to one of your own, while she was on maternity leave is completely devastating."

Nicole had emergency surgery, eleven hours worth, and is still recovering.

Naturally, doctors haven't cleared her to get back to work yet.

But Pendleton had an idea to lift her spirits.

"So I though how cool would it be to surprise her with the Three North family."

A team of more than 20 nurses and hospital staff choreographed a surprise dance to Katy Perry's "Roar."

The set up the 'flash mob' in Nicole's mother-in-law's backyard.

"They told me I needed to go outside," she said. They lured her out with the promise of a deer feeding in the backyard.

But there wasn't a deer.

Instead three of her co-workers galloped from hiding and started to dance to the song.

"I walk outside, the music is playing and I'm shocked."

But right as the song hit the chorus, 20 more co-workers ran out ... and the flash mob was on.

"Of course, that's when I started crying."

It was a reminder, Pendleton said, that Three North is still there and still love her.

"That's the biggest thing we felt in that moment," Pendleton said, "It was love."

It was a few moments of happiness until she can get back to work at Three North.

"It makes you forget all the other stress you have," Nicole said. "All the worries, everything."
