How has God brought you to where you are today?

Ryan and Heidi both experienced a call to share the Gospel with others overseas when they were in High school. They have served in Portugal, Mozambique, Malawi and now live in Chiang Mai, Thailand. Ryan is the mission Director, Heidi is the Personnel Director.

What is God doing in your immediate context?

The church in Thailand is small (less than 0.5% of the population), but is active in reaching out to their neighbors with the Gospel. We are active in leading SIM in ministries of church planting, equipping the church to minister and supporting missionaries in the region.

How does your partnership with Calvary help you be more effective in your work?

We see ourselves as an extension of the body of Christ at Calvary serving overseas. The financial and prayer support of the saints at Calvary enable us to minister, persevere and bear fruit.

How can people stay connected with you and your ministry, e.g. email newsletter, blog, social media?
