Pastor John Hadley is originally from Chelmsford, Massachusetts, and is the second of eleven surviving children. Raised in a Catholic home, he became a born-again believer in Jesus Christ in 1976. His faith has since influenced many in his family, including his parents and several siblings.
In 1976, John joined the Peace Corps and served for two years in Guayaquil, Ecuador, as a machine shop instructor at the Politécnica. During this time, the Lord brought many believers and missionaries into his life, helping to shape his calling for ministry.
After returning to the United States, John met his wife, Nancy, and they were married in 1980. They have four children.
He later attended Stevens School of the Bible and was ordained as a minister of the Gospel in 1983. John is fluent in Spanish, and he and his family served as missionaries in Ecuador from 1985 to 1990, establishing a church in Guayaquil that continues to serve its community. He went on to become Dean of Students at Maryland Bible College, where he also studied, and later earned a Master of Arts in Biblical Counseling from Luther Rice University and Seminary. He continues to serve in leadership at Maryland Bible College and Seminary and as Head of Counseling at Greater Grace Church in Baltimore.
In addition, John has served for more than a decade as a volunteer chaplain for the Baltimore Police Department, Northeast District, with involvement in community outreach and ride-alongs supporting officers.
