On November 17, 2020, Marijo won her 32-year battle and is walking and dancing in Heaven. She was an inspiration to everyone who knew her with her tenacity, courage and determination never losing her faith and hope. Marijo was born in Butte, Montana to Patrick and Romana O'Leary in 1944. She graduated from Girl's Central Catholic High School in Butte, Montana where she met her husband, Joe Sullivan. She graduated from Great Falls School of Nursing with an RN degree. Marijo married Joe Sullivan in 1967 in Montana. They moved to Boston, Massachusetts after they were married where she was a nurse. In 1969, they moved to Kennewick, Washington where Joe accepted a teaching job and they have resided there ever since. During this time, she spent many years raising a family and practicing her profession with caring and compassionate dedication as a nurse for the Kennewick School District. Her passion was for migrant school children and she was their advocate beyond her job. She enjoyed being a part of her children's sports and activities as well as getting together with her multitude of local friends for social events. In October of 1988, Marijo suffered a massive brain hemorrhage that left her in a wheelchair and in the care of Joe and many caregivers for the rest of her life.
