Steven had the opportunity to teach at Servant of Christ Theological Seminary, which was started by a group of Chinese churches in São Paulo. This school has the vision to reach Chinese immigrants in Brazil, to prepare leaders for Asian churches in Brazil, and also to send missionaries to Taiwan and China. Steve says, "It has been exciting to have a part in training and mentoring leaders for the church in Brazil, as well as workers who will eventually go to other parts of the world."

During their first term, Mary Ann helped in the kindergarten class at Pan American Christian Academy (PACA), the local missionary children's school.

Mary Ann also worked as a group leader in a women’s Bible study, and later taught Bible lessons to pre-school children while their mothers attended the Bible study. "Young children are open to the gospel and have a lifetime of service ahead of them. It makes sense to try to reach them for the Lord," says Mary Ann.
