Most Swim Across America participants wear their SAA swag with a sense of pride of making an impact in their community. For Natalie Thompson and her family in Nantucket, Massachusetts, it’s more than just an event — it’s a way of life.
“Swim Across America – Nantucket gear is a badge of honor on this island. We swim for the people we see everyday — our neighbors, our friends, and our family — so we can make their fight easier,” said Natalie.
Swim Across America – Nantucket gives grants to on-island cancer treatment and care at Nantucket Cottage Hospital and Palliative and Supportive Care of Nantucket. It also supports glioblastoma research at Mass General Cancer Center in Boston. The unique offering of on-island care allows patients fighting the toughest battle to remain close to home while receiving outstanding treatment.
When it comes to SAA gear, Natalie and her family have plenty. Since 2012, she has participated in the event — in every and any capacity — alongside her wife, Cassie, and their two sons.
“I’ve been part of the setup crew, the breakdown crew, an angel swimmer, a 4-miler… whatever I can do, I do,” said Natalie. “My wife has always volunteered, and now she runs the Falmouth Road Race to support our swim. SAA is just part of our lives. We do it as a team to support our amazing community.”
Natalie first joined SAA-Nantucket to honor her grandmother, who fought breast cancer. As the years went by and Natalie remained involved, cancer would hit close to home not once, but twice more.
“June 2019 changed why I swim for the rest of my life. My wife was diagnosed with ocular melanoma at 33. We had two young boys at the time, and suddenly, we were facing cancer head-on,” she shared.
“Eight hours after she was diagnosed we attended a Swim Across America event and I knew we had a support system like no other. No one at the event knew that night of her diagnosis but I left having hope that we would make it through it all. This was the first summer I participated in the 4 mile swim and it was even more impactful having my wife as my kayaker.”
Less than a year later, Natalie’s family was hit with more devastating news.
“In March 2020, our world was rocked again. My dad was diagnosed with stage 4 renal cancer,” Natalie said.
“As soon as I heard the news, Jill Roethke and Jim Pignato, SAA-Nantucket co-event directors, were my first call. The world was shutting down due to COVID, and my dad needed tests to begin treatment. They got me connected to the right people, and in that moment, I knew our family had endless support from our Swim Across America family.”
For as long as SAA-Nantucket is around, Natalie and her family will be there, supporting the mission and their community — a value she’s proud to pass on to her sons.
“SAA’s impact on the Nantucket community as a whole means that no one fights their cancer battle alone. We are a community on a little island ensuring that cancer patients spend their invaluable time with their families and friends instead of countless hours traveling for treatment elsewhere.”
“My kids have grown up attending the event, and it’s incredible to teach them about this special support system. They know I swim for their grampie and mom. It’s a special moment every year when I finish the 4-mile swim to have my kids see me finish.”
