The Ron Williams family was appointed in 1969 as Foursquare missionaries to Hong Kong where Dr. Williams served as Supervisor of the Hong Kong and Macao Foursquare work from 1973 to 1985.

After serving for several years as a linguist with the U.S. Air Force, which responsibility necessitated a lengthy time of service in Asia, Dr. Williams returned to the United States to study at L.I.F.E. Bible College where he graduated in 1965. With his wife, Carole, and family, he ministered in Western Canada in such capacities as pioneer pastor, Bible college faculty and youth ministries.

Such varied experience proved valuable for the Williams, as their ministry in Hong Kong included supervision of churches and pastoral care; social concern ministries, such as a Christian high school of over 500 students; the Macao Foursquare Gospel Children's Home; and counseling care to the elderly, as well as outreach to the People's Republic of China in cooperation with other religious agencies.
