Kamran Karimi founded The Voice of Freedom in 2000. As an American citizen born in Iran, Kamran accepted the call of God to serve the Lord and the people of his native country. Iran is a closed-door nation where the Gospel cannot be preached openly, and as such, it requires a unique wisdom for reaching its people.

In 2003, the ministry began airing a weekly program entitled Nedae Azadi, which translated from Farsi to English means The Voice of Freedom.

By 2006, the ministry began airing the program daily, and its influence has become significant in helping to reshape the culture of Iran and the lives of Iranians. It has been the key instrument in causing the fastest-growing underground house church movement in the world taking place in Iran.

The Voice of Freedom has evolved into a church-planting organization established to help equip Iranian nationals, reshape Iranian culture, and establish freedom in the Iranian social climate.

The ministry also raises awareness among Western churches and governments concerning the spiritual and natural effects of Islam on people and cultures and how to deal with Islam.
