Welcome to the Swim Across America - Seattle Open Water Swim! Established in 2009, SAA - Seattle has raised over $3.4 million for our beneficiary: Seattle Cancer Care Alliance. Thank you for your support of cancer care in Seattle.

We are so excited to have you join us for our 14th annual swim on September 10th! NEW 2021 VENUE: The swim will be held at Swim Beach at Warren G Magnuson Park.

Proceeds from the swim support immunotherapy clinical trials and cancer research at Seattle Cancer Care Alliance.

Hear directly from the incredible doctors your funds are supporting below.

Seattle Cancer Care Alliance (SCCA) brings together the leading research teams and cancer specialists of Fred Hutch, Seattle Children's, and UW Medicine. When you seek treatment at SCCA, you access an extraordinary group whose sole mission is the pursuit of better, longer, richer lives for our patients.

For the past eight years, the Seattle chapter of SAA has generously supported research at SCCA, raising nearly $2.0 million to directly benefit the Pancreatic Cancer Specialty Clinic and the Swim Across America Cellular Therapy Lab. Last year, volunteer efforts bridged funding gaps; accelerated research in pancreas cancer—an area of exceptional need; and supported immunotherapy—an area of great promise.
