Mark and Laura Ambrose serve with Mission to the World in Phnom Penh, Cambodia, where they focus on church planting and anti-sex trafficking initiatives. After two decades of providing medical care in the U.S., Mark transitioned to serving marginalized populations in Cambodia, particularly victims of sexual exploitation. He leads Family Clinic, which not only provides essential medical services, but also trains Cambodian Christian doctors to practice gospel-centered medicine. This clinic is integral to their church-planting efforts, as it connects healthcare with local churches, facilitating outreach and support for people in need.

In response to the challenges faced by young women exiting rehabilitation programs for trafficking survivors, the Ambroses founded Freedom Ministries. This initiative offers scholarships, housing and discipleship through local church dorms for college-aged girls. Secondly, there is Dahlia Dorm, a home for younger girls aged 10-18. Freedom Ministries aims to integrate these young women into the church community, providing them with a safe environment where they can heal, grow, and develop their faith. Through their combined efforts in ministry, Mark and Laura Ambrose are making a significant impact on the lives of those they serve in Cambodia.
