David & Anne Sheahan have been with OMF Thailand since 1990. Until 2005 they were part of the Central Thailand church planting team, working in Saraburi, Phichit, and Nakonsawan provinces. In 2006 they moved to the church planting work in Chiangmai, and began teaching at Chiangmai Theological Seminary in 2010. Their home is the United States, with roots in both the states of Wisconsin and Alaska. They have three grown sons, each now living in the States.
While David and Anne were each completing degrees at Trinity Evangelical Divinity School and Multnomah School of the Bible respectively, the call to serve in missions took root and led to their eventual application with OMF. Once married and part of OMF, it was friendships with Thai and OMF missionaries in Thailand that led to them join the Thai team.
