Missionary Profile

Ministry Focus

Sam and Becky live in the Phoenix, Arizona, area, where they serve seeking to reach community college students with the truth and love of Jesus Christ. Their goal is to get students into God’s Word and God’s Word into students so they will come to faith and grow in faith in the Lord Jesus. They have been in campus ministry in Arizona with Missions Door since 1995. They have found that the college campus is perhaps the most open area in the United States for sharing Christ. The needs are great. The false teachings, philosophies and appeals to the flesh draw many into lifestyles from which they never escape. Statistics show that even among church-attending kids up to 90% leave the church and most leave the faith by the time they graduate from college. Sam says, “Campus ministry is vital because students are at perhaps the most pivotal place in their lives. Most of them are looking for answers to the biggest questions in life. It is also the last really open time for reaching them with the Gospel.”

Faith Story

While reading the Bible in Pennsylvania at the age of 22 Sam came to see that, “if Jesus Christ means anything in my life, He must mean everything!” So he surrendered His life to the Lord. With a desire to serve God, he enrolled at Southwestern Bible College in Phoenix, Arizona, to prepare to serve on the foreign mission field. While attending Southwestern, he met Becky whose parents were missionaries with World Venture in Brazil where she grew up. After Sam graduated from Western Seminary, Sam and Becky served as church planters with World Venture in northeast Brazil for eight years.


Sam and Becky were married in Brazil during a short-term mission experience while in college. They have three sons, Samuel, Joshua and Micah.

Iconic American traditions include Thanksgiving dinner, jazz music and the Super Bowl. They meld with eclectic examples of multicultural heritage: numerous local Chinatowns, family-owned taquerias and even cowboy boots, which originated among the nomadic Huns of eastern Europe.

The nation's landscape shows just as many contrasts — sandy beaches and rocky coastlines, open plains and vast deserts, rugged mountains and winding canyons, and abundant rivers and lakes.

The ideals of life and liberty that founded the United States have made the country one of the world's most prosperous, though not without dark chapters and present troubles. Crime, discrimination and ethics violations make regular headlines, and many people live below the national poverty level.

Families view education as essential to the pursuit of happiness, if not also a path to wealth and power for the most ambitious. Yet Americans also demonstrate a charitable spirit of generosity toward neighbors and nations in need.

Freedom of religion grants opportunity for all faiths, but Christianity holds particular influence in country's history and daily life.
