Our Story

Whitney Marie was born on September 27, 2011 at 1:02 am as a beautiful, healthy 6 lb. 12 oz. girl. On November 1st, at five-weeks-old, we noticed blood in Whitney's urine and went directly to the emergency room where a sonogram detected a "mass" in her right kidney. At six-weeks-old, Whitney had her entire right kidney removed at Memorial Sloan Kettering Cancer Center and the mass was diagnosed as a Malignant Rhabdoid Tumor of the Kidney. This extremely rare and aggressive cancer affects young children and only five to ten cases are diagnosed in the US each year. At seven-weeks-old, Whitney started her first chemotherapy treatment.

After a brave, ten-month battle, Whitney passed away peacefully on October 8, 2012. Although she was here briefly, her life significantly impacted many people around her. She taught us that regardless of the circumstances, we must always BELIEVE!
