'Vocal zone is the best thing I have ever used for my throat. As a singer and public speaker, I would not even function without it. Vocal zone is the perfect size. It is simply fantastic!' - Heidi Baker
Heidi Baker PhD is a Christian missionary who co-founded Iris Global, a non-profil Christian ministry dedicated to Jesus and service and released several books. Heidi and her husband founded IRIS Ministries in 1980. After twelve years of ministering in Asia, they left in 1992 to do their PhD's at King's College London, UK. In 1995 they started a new ministry to the poor and homeless children in Mozambique. The ministry has expanded to include well-drilling, free health clinics that service the poor and sick, feeding programs, primary and secondary schools, cottage industries and now over 5000 churches in Mozambique and a total of over 10,000 churches in over 20 nations.
Originally from Southern California, the Bakers are now based full-time in Pemba, Mozambique. They also travel to various places around the world to share their story, and to teach about God's love and what love in action looks like. The core value and message of the Bakers ministry is God's love.
