LeightonCurrent Ministry

We are the field directors for OMF Thailand – a joy, a challenge, a privilege! A joy because we have a bird’s eye view of what God is doing – building His church as never before! Half of all the churches in Thailand were started in the past 15 years! A challenge because there are still too many unreached communities. A privilege because we get to work with 180 dedicated missionaries from at least 15 different countries.  With a leadership team, we set direction for evangelism, disciple-making, church planting, and support ministries. We train and develop missionaries, as well as church leaders. We serve on boards, like the Associated Churches in Thailand or Bangkok Bible Seminary. We pray for God’s work.

How did we get to this point?

In high school, we were both challenged to consider Jesus as Savior and Lord. Mark came from a Christian family, Becky from a non-Christian family. Separately, we both yielded to Him; His Lordship has been the defining factor for our lives ever since. At university Mark helped start a Christian student group. That is where we met. Evangelism and disciple-making were an important part of our university experience. After we married, we also started a house church.

Later the Lord led us to take up an assistant pastor role in a traditional church for 5 years. One of the significant responsibilities while there was to organize the annual Missions Conference. At each Conference our own hearts were touched until we finally had to say, “Lord, send us!” So, in 1985 we joined OMF and moved our family of 3 boys to Thailand!

From 1985-1995 we worked in Central Thailand, helping to establish 2 churches. From 1995-2007 we served as regional directors in Central Thailand. In 2007 we were appointed field directors of OMF Thailand.

Our educational background is as follows: BA from Lewis and Clark College in Portland, Oregon in 1974. Mark received his masters of divinity from Western Conservative Baptist Seminary in 1978.  Becky studied 2 years at Western. Mark completed the doctor of missiology degree at Trinity International University in Illinois in 2000.


A particular need for OMF Thailand is mobilization of people! Church-planters, student workers, disciple-makers… The Thai government issues work permits for us to teach the Christian faith! There are many needs and opportunities. How do we get the word out? We need a full-time mobilizer to share what God is doing in Thailand through all kinds of media and to connect with Christians from anywhere in the world whom God may be preparing to serve Him in Thailand. He is the Lord of the harvest and so we ask Him for more workers.
