Sky St. John spent the majority of his adult life in Honolulu where he was a public school teacher for thirteen years before answering the call to become a Unity minister. He returned to Hawaii to the dynamic Unity Church of Hawaii in July 2005. 

Sky also had a successful entertainment career, performing at the Hilton Hawaiian Village for fifteen years and producing several professional recordings. He became a Registered Nurse and worked for two years in the last existing leper colony in the United States, on the island of Molokai. After teaching nursing at the college level, Sky formed a nursing education company called "Operation Nightingale," training international nurses from all over the world.

He holds degrees in education, communications, nursing, with graduate work in Health Education and is A.B.D. (all but dissertation) for a Doctorate in Public Health. He was the builder and owner of a bed-and-breakfast on the Big Island of Hawaii until his call into ministry in 1994.

Graduating from Unity Seminary in 1995, he worked as a Minister in the Retreat Department at Unity Village for two years. During that time, he was also the Music Director for the first Unity World Conference and traveled throughout the country presenting workshops, concerts and Sunday services. Sky then spent the next five years in Omaha, Nebraska as the minister at Unity Church of Omaha, where they grew from a congregation of fifty to nearly five hundred. Their stated mission was: to realize our oneness with God and each other, and this is still a mantra for Sky.
