Drs. Kosj and Jaymi Yamoah started Out of Zion, Inc and Hope4ATRT after walking through their own cancer journey as a family. In 2015 their almost three-year-old son, Zion, was diagnosed with a rare and aggressive form of brain cancer known as Atypical Teratoid Rhabdoid Tumor (ATRT). Even as an oncologist himself, Dr. Yamoah was dismayed to learn how limited resources were for this rare disease. After the devastating loss of Zion, his parents were compelled to help fund innovative research, and be a resource for families in the fight against ATRT.

ATRT is a very rare, fast-growing tumor of the brain and spinal cord. The disease commonly affects children age 3 or younger but can also affect older children and adults.
