Sam George was born in a Christian home in the Andaman Islands of India. His heritage comes from the St Thomas Christians of Kerala, India, and he had a life-changing encounter with Jesus Christ at the age of 15. After completing a BE in mechanical engineering and a MS in business management in India, he spent nearly ten years in the field of computer-aided design software in different parts of Asia and the United States. After sensing a call to Christian ministry, he began theological studies at Fuller Theological Seminary (where he was introduced to the Lausanne Movement) and later at Princeton Seminary.
Over the last two decades, God has used Sam to pioneer two family-oriented mission organizations, Urban India Mission in Bangalore and Parivar International in the Chicago area. He completed his doctoral research in diaspora missiology and theology at Liverpool Hope University (with Andrew Walls as one of his advisors), and has taught modular courses in Bible colleges, seminaries, and universities in Asia, Africa, Europe, and North America.
Sam served as a subject matter expert for the diaspora track at the Lausanne Cape Town 2010 Congress, and has contributed regularly to regional and global diaspora consultations, including the Global Diaspora Forum in Manila in 2015. Sam currently serves as a Lausanne Catalyst for Diasporas.
