Jon and Diane Barr have been missionaries to deaf people since 1984. They are graduates of Bob Jones University. In 1976, Jon learned Sign Language from a missionary who came to his church in Florida, and later, became a certified interpreter. Jon and Diane were married in 1981, and served at Palm Springs Drive Baptist Church in Altamonte Springs, Florida, as Pastor to the Deaf and Christian school teachers under Pastor Loyal Carlson. Palm Springs Drive Baptist is the Barr’s missionary sending church.

In 2000, the Barrs merged their missionary work with SWM, and Jon Barr was appointed by Ted Camp to be the president. Jon brought his expertise in the areas of the Internet, videos, computers, Sign Language and Deaf ministries. He produces SWM videos, DVDs, and the web page, and assists in all areas of the ministry. Diane, his wife, serves as the bookkeeper, assisting in office operations. She serves on the Executive Operating Board. Jon Barr is able and qualified to continue the operations of SWM. The Barrs’ burden is to start deaf ministries, strengthen existing deaf ministries, and create materials which can be used to teach deaf people the Good News of God’s Word. Their two adult children, Rebekah and Joshua, also know Sign Language.
