Winston Bui was born in Saigon, Vietnam. He fled the country as a refugee on the day of the fall of Saigon on April 30th, 1975 and later arrived in the US. After settling in Oklahoma, he discovered Christ as a teenager at a youth service. He graduated from Northeastern State University in Tahlequah, Oklahoma and became one of the nation’s top campus ministry leaders through Chi Alpha campus ministries. He established and led Chi Alpha chapters at his Alma Mater in Oklahoma; the University of Missouri; the University of California, Los Angeles; and the University of Southern California. He has also served as the West Coast Area Director for Chi Alpha campus ministries.

Having experienced first hand the unthinkable horrors of war and the challenges of refugee life, Winston has a deep passion to help those in desperate need and to see them thrive. His life experience, compassion, and practical humanitarian approach to challenging situations have allowed him to impact communities around the world. His many personal encounters with the devastating effects of war, poverty, and hunger have also made him a highly sought-after speaker who boldly advocates for the needs of the orphans, the widows, the marginalized, and the outcast, and actively seeks to facilitate practical solutions to their challenges. 

Winston has led many missions teams all over the world, including Haiti, Mexico, Vietnam, China, and throughout Europe. He has led more than 49 teams to invest in the small village of Fond Doux, Haiti for over two decades.
