Kenneth Joseph Sullivan was born in New York City, on December 13, 1926, near the present location of the United Nations Building. He was the only child of Eugene and Veronica Walsh Sullivan. After a year, the first of many moves occurred in Father Sullivan's life, for he and his family moved to the South Bronx where he started school. Then, there was another move to Queens, New York, where he entered the School of Our Lady of Mt. Carmel in Astoria, from which he graduated in 1943. He then attended La Salle Academy, a high school run by the La Salle Brothers of Christian Instruction. It was here that he first considered and became interested in becoming a priest. After hearing a conference given by Monsignor George Carroll, M.M., he decided to enter Maryknoll.
In 1944, Father volunteered to enter the United States Navy. He was accepted and became a hospital corpsman. He served in the Navy for twenty months. He reapplied to Maryknoll and was accepted to enter the Maryknoll Minor Seminary in Brookline, Massachusetts in 1946. He then attended Maryknoll Junior College in Lakewood, New Jersey, for two years and then Maryknoll Seminary for six years. He was ordained at Maryknoll, New York, on June 8, 1957.
After ordination, he was assigned to the Maryknoll Mission in Africa to work in the new Diocese of Musoma, Tanzania, which had been established that same year. Shortly after his arrival in September, he attended the consecration of Bishop John Rudin, the first Maryknoll Bishop of Musoma. Father Sullivan was assigned to the newly opened mission of Zanaki, named for the people who lived in the area. This mission became his home for five years as he settled in to learn the language and customs of the people who were the Zanaki tribe. There were several changes of assignments to different missions after that but Zanaki was the beginning of his work in Tanzania.
In 1978, Father Sullivan was assigned to the United States Region and the Development Department for work in the St. Louis, Missouri area. His three-year assignment was extended for one year until 1982. Father Sullivan was then assigned to start a student program in St. Louis for Maryknoll candidates on the college level. After one year, Father Sullivan was reassigned to Tanzania.
In 1986, he was again assigned to the Development Depar1ment and this work brought him to Washington, D.C., St. Louis, Florida, Chicago, and Seattle.
Father Sullivan returned to Africa in 1989 and is presently working at Mwisenge Catholic Church in Musoma Diocese , Tanzania
