AMMON — Ammon Mayor Sean Coletti has proclaimed Sept. 8, 2025, in Ammon, as “Tanner Scoresby Day,” in honor of the local teenager fighting for his life.

Scoresby, 18, is an Ammon resident and Thunder Ridge High School graduate. He was diagnosed with T-cell lymphoblastic lymphoma, a type of blood cancer, earlier this year. After five months of chemotherapy, it was discovered that the mass on his heart and lungs hadn’t shrunk at all. He’s currently in Arizona to receive a stem cell treatment.

One of Scoresby’s family friends previously told EastIdahoNews.com, “It’s a treatment that people who have Tanner’s type of cancer, that chemo hasn’t been successful for, this has worked.”

“I know there are a lot of people who are pulling for him right now in Ammon,” Coletti told EastIdahoNews.com. “
