About Us

Frontline Missions develops and cultivates partnerships within the global church to train and equip followers of Jesus to reach the nations for Christ.  We do this by tailoring creative solutions to the specific needs of each country, village, and person we encounter.  We currently operate in seven countries in Central and South America, helping people in underdeveloped regions with solutions like Bible storying, leadership training, and economic development.  This opens the path for self-sustainability and self-transformation through relationship with God.

History of Frontline

Frontline Missions’ founders, Alan and Heidi Winter, began taking youth on mission trips in the mid 1980’s. After a few years, they realized there was a huge need to take others on mission trips and train them to be culturally sensitive.

Alan and Heidi’s aim was to train teams to be a blessing to nationals and ministry partners in other countries. Frontline Missions began in 1997 by training groups from churches and Christian schools on the cultural aspects of missions and giving them the opportunity to serve in practical ways.

Alan Winter, President & Co-founder of Frontline Mission

For over twenty years, Alan Winter poured his life into the Great Commission, connecting and inspiring the global church to love the one in front of them.

Alan’s desire to fully express the love of the Father in every moment with every person culminated in a life of radical obedience that saw thousands enter the Kingdom of God.

The ripple effect of Alan’s ministry continues to bear fruit in the lives of every person he encountered, from flight attendants to indigenous leaders in remote villages.

In early 2017, Alan suffered a stroke while flying to Colombia with a mission team. A few days later, in a room filled with family and friends, Alan was ushered into Heaven with heartfelt worship.
