Wanda Maloy, Operations Manager  

Every day working as ASM’s operations manager is different, and that is probably why Wanda loves the job. She considers it an honor and a privilege to be a part of the ministry. When she is not working, Wanda enjoys vacations with her husband and family, outdoor activities three seasons of the year, and reading by a fire in the fourth one. She also enjoys hanging out in downtown Holland, MI.


Joshua Harrison, Communications and Development Manager  

“Can you please read it to me again? I’ve never heard that story before, and I just want to close my eyes and listen to it again.” Joshua will never forget that moment, as a neighborhood friend heard the story of Jesus for the first time. Joshua grew up on the mission field as a “third culture kid” and saw first-hand the power of God’s Word heard in someone’s own heart language. The Holy Spirit uses it to transform lives, whatever a person’s cultural context. Ever since he realized his own great need for Jesus, Joshua’s passion continues to be for the least-reached and Gospel-destitute people of the world.

Before joining ASM, Joshua’s background was in promotions and radio broadcasting, with a master’s in Applied Linguistics from the University of Massachusetts, Boston, and a bachelor’s in Applied Linguistics, ESL, and Bible from Moody Bible Institute.

As ASM’s Communications and Development Manager, Joshua has the privilege of sharing the stories of God at work across the world, and inviting others to join in with what God is doing. His desire is to develop the partnerships and resources needed to reach every person still waiting to hear God’s Word, so together we can delight in our Savior and faithfully fulfill His Great Commission.

Listen to Joshua share a brief Scripture encouragement during ASM’s “Home in His Word” project.


Chris Billquist, Resource Department Coordinator

Chris is a graduate of Hope College (Holland, MI) where he studied Religion, Psychology, and Ministry. He then studied at Western Theological Seminary (Holland, MI), before joining the team at ASM. In his current role at ASM, he enjoys drawing from his interests in ministry and mission, teaching, social justice, and information management. Previously, he has also taught in several West Michigan grade, middle, and high schools as a teacher’s aide and substitute teacher. In both ministry and education contexts, he has witnessed the difficulties faced by many in our communities who must overcome challenging home situations or economic circumstances. Chris is passionate about the Christian call to respond to these needs as Jesus would, so that all people, regardless of socioeconomic status or life circumstance, may see their dignity, their worth, and “may be filled to the measure of all the fullness of God” (Ephesians 3:19, NIV). Chris’s desire to help people overcome language and literacy barriers worldwide is expressed through his work at ASM, where the mission is to help “[provide] the Bible in audio that all might have the opportunity to hear God’s Word in their own language.”

In his free time Chris loves spending time with family and friends, reading, enjoying nature, singing, and supporting/participating in the theater arts.

Chris is an active volunteer in his local church, serving on both the worship team and in children’s ministry.

Listen to Chris share a brief Scripture encouragement during ASM’s “Home in His Word” project.


Jonathan Verastegui, Accounting Coordinator  

Jonathan enthusiastically combines his love for ministry with his daily work, as he applies his skills and education to follow the calling God has put on his life. He is a graduate of Davenport University with a bachelor’s degree in Business Administration, and has work experience in sales, administration, and customer service. Jonathan grew up in a Christian family that prioritized the work of the ministry, and he continues to be actively involved. He currently serves as a Co-Pastor of New Life Nazarene and as a board member for the Holland-based nonprofit, Harvest of Generosity. For Jonathan, being part of the ASM team means more opportunities to help share the Word of God with those who have not yet heard.


Sarah Aron, Social Media and Design Coordinator  

Sarah started working with ASM in the year 2015. Sarah and her husband Patrick had been interested in Audio Scripture Ministries for a couple of years and had been trying to find a way to partner with what they believe is an inspiring and worth-while mission. When she’s not at work, Sarah designs graphics for New Chapel church in Grand Rapids, and Lifepointe Church in Clarksville. Her attention to detail and eye for graphic-design are skills that we are excited to have as part of our team. In her spare time you will often find Sarah curled up in a sunny spot with some tea, a good book, and whatever craft she currently has going.


Lloyd Wolters, ASM Representative  

“There are so many people who can’t read God’s Word for themselves, but now they can hear God’s Word with these audio players.”

ASM Representative Lloyd Wolters desires everyone to hear God’s Word and come to faith in Jesus Christ. Lloyd’s father introduced him to ASM Founder Ron Beery. After hearing ASM’s vision for audio Bibles 45 years ago, Lloyd’s passion to share audio Scripture was confirmed during a 1990s visit to India when one man thanked him for bringing audio Bibles
saying, “You brought us from darkness to light, from despair to hope.”

Lloyd advocates for audio Bibles and he uses them! During 34 years as a pastor, Lloyd often used a hand-crank cassette player—and later, a digital audio Bible—to play the Scripture passage being used in his sermon. Today, Lloyd carries an audio Bible with him, always ready to share God’s Word with someone who needs it.

Lloyd’s favorite verse is Romans 10:17, where Paul reminds us, “How can they hear without someone preaching to them?” Lloyd joyfully notes “every one of these audio Bibles is a preacher, an electronic evangelist.” Lloyd encourages everyone, regardless of age, to consider investing their free time and available resources in sowing the life-giving, priceless gift of God’s Word in audio. God has faithfully blessed Lloyd’s work, bringing Bibles to more people around the world, and empowering many others to pray for and support ASM, so that all may hear. ASM thanks God for Lloyd!


Don Lang, ASM Representative  

Over the past five years, Don Lang and his dedicated friends in Oregon have helped send more than 1,000 audio Bibles to some 17 countries, connecting thousands of people to God’s Word in audio! Don’s connection to ASM began after he experienced great personal loss, and felt called to pray Psalm 71:18 (NLT): “Now that I am old and gray, do not abandon me, O God. Let me proclaim Your power to this new generation…” The answer to this prayer came in part through a businessman in Bend, Oregon who encouraged Don to give away two audio Bibles. Since then, God has opened doors for Don and led him to build vital ministry connections—like with Kingdom Air Corp, the Free Burma Rangers, and many others—as Don saw the incredible impact of each Bible in audio.

“How many people will each audio Bible reach?” Don ponders. “Perhaps 10…or maybe more? Only God knows how many. And in that number, is there a next ‘Billy Graham’ for Burma, or for Uganda?”

This is Don’s prayer—that every person who listens to an audio Bible will put their trust in Jesus and lead many others to the Lord. When Don isn’t representing ASM or helping connect more people to God’s Word in audio, you’ll find him spending time with his kids and grandkids, active at his church, or outside enjoying God’s beautiful creation. Don describes himself as an “ordinary” and “naturally shy” person, but to the ASM Team he is a champion in the cause of reaching people around the world! We praise God for Don and the team in Bend, Oregon.


Mexico Team Members

Jim and Jamie Loker, Latin America Directors  

Jim and his wife Jamie have served in full-time missions since 1986; first in Guatemala, then Oaxaca, Mexico, and currently at the home office of Audio Scripture Ministries in Holland, Michigan. Their main role is to coordinate the recording and distribution of audio materials in Mexico. To date, the recording ministry they founded in 1994 has produced 85 complete New Testament recordings and 50 dubs of Jesus films in the indigenous languages of Mexico, as well as many Old Testament portions, stories, and summaries. Through local church leaders and team trips, the Lokers have distributed thousands of audio Bibles in over 80 language areas.

The Lokers have seven adult children and ten grandchildren scattered across five time zones and three countries. Besides family, Jim and Jamie also enjoy hosting short-term teams, sharing their passion for reaching indigenous people groups with scriptures in their mother tongue. Jim’s favorite hobby is talking to internationals he meets while in the U.S. and showing them how to access phone apps with audio and video scripture materials. Jamie’s pastimes include reading, writing, and intercessory prayer.

To learn more about Jim and Jamie and the ministry work they’ve done, visit their blog at lokerministry.blogspot.com

Listen to Jamie share a brief Scripture encouragement during ASM’s “Home in His Word” project.


Diego G, Coordinator of Technology  

At age 20, Diego’s studies in computer technology landed him a job at a federally-run radio station focused on multilingual broadcasts to different ethnic groups. There he learned more about the diverse people groups of Mexico and their languages. God was preparing him! As he became involved in a local church, Diego responded to the Lord’s call to full-time ministry.

“Here we are, Lord. Send us.” Shortly after their wedding in 2010, Diego and his wife Luz humbly accepted the invitation to move from Baja California to Oaxaca, Mexico. They had met at seminary while preparing for pastoral ministry, but when they heard about the need for a recording technician, they prayerfully discerned God’s leading.

After two years of traveling throughout Oaxaca state, recording, editing, and distributing audio Scripture materials together as a couple, God blessed Diego and Luz with their first child. They started a church in Mitla, close to the recording studio. Today they have three young children, and their thriving multicultural congregation is doing outreach in a neighboring village.


José and Jemima G, Recording Technician and Distribution Coordinator

José (called “Lupe”) and Jemima G are two key ASM team members in Mexico. Their kind and patient attitude is a testimony to everyone. Together they are involved in almost every ministry aspect. They help identify languages that need the Bible recorded, meet with local pastors and leaders, and set up temporary recording studios in villages.

Next, they help produce, edit, and process the Bible recording. Finally, they often return to help distribute the audio Bibles. Lupe and Jemima first met during the multi-voice dramatized recording of the Guerrero Nahuatl New Testament. Jemima was reading several of the women’s parts and Lupe was the recordist. Lupe has served on the team since 2008, and Jemima joined in the work full-time after their marriage on Valentine’s Day 2015.

In spite of the hardships faced when traveling to and recording in remote locations, Lupe and Jemima consider it a privilege to share God’s Word all over Mexico. They take great joy in fellowshipping with other believers, and witnessing the tears of joy when people receive and hear the audio Bibles for the first time in their own language.


Isaias M, Recording Technician


Edi M, Recording Technician


Mozambique Team Members

Chad Vanden Bosch, Africa Director  

Nearly one billion people worldwide can’t study the Word of God because they can’t read, and this is especially true in the country of Mozambique, where just 20% of the population is literate. As director of African operations for ASM, Chad oversees audio Scripture training, recording, and distribution projects throughout Africa, particularly in Mozambique. He travels from his base in Mozambique to new project locations in order to set up recording and distribution programs and train personnel in recording equipment and techniques.


Sergio Muianga, Director of Xai-Xai Studio  

Sergio Muianga has been pastoring since 2002. In 2003, he saw how positively people responded to audio materials in their own language. After he finished studying at the Wesleyan Bible College, Sergio felt the Lord calling him into the ministry of helping people hear God’s Word through recording and distributing it.

In 2005, he began working with this ministry, because “many do not have a chance to read a Bible, and it is often difficult to get a written Bible. But an audio Bible makes it accessible to all.”

He especially enjoys the technical aspects of editing the audio to make it as good as possible, so when many people listen, they will all enjoy a high quality recording. Sergio and his wife, Juliet, and their three children live in Xai-Xai, Mozambique.


Estêvão Macambaco, Recording Technician and Distribution Coordinator  

“Commit your way to the LORD; trust in Him, and He will act” (Psalm 37:5, ESV) is one of Estêvão (Steve) Macambaco’s favorite Bible verses.  Steve says this verse is an important reminder that God is our Provider: “We need to give everything to God and have confidence that He is the owner of everything and has promised to take care of us.”  Since trusting God means hearing and remaining in Jesus’ Words (John 15:7), Steve has a heart for bringing God’s Word to people in an accessible way, in their own mother tongue.  

As a young man, Steve first came to know Jesus through a church choral group.  In 1998, he dedicated himself to full-time Christian service. Today, he serves as senior pastor at the Parish of Chinunguine (Emmanuel Evangelical Wesleyan Church) and as National Secretary of the Wesleyan church in Mozambique,as well as Recording Technician with Mozambique’s Associação das Escrituras Em Audição (Association of Audio Scriptures).  Steve has seen firsthand the impact of audio Scripture. He reflects that “hearing the Word of God in audio has been a blessing in my [own] life. Audio allows you to hear the Word almost anytime and anywhere, and especially benefits those who have never had the opportunity to go to school.”

Steve and his wife, Inência, have been married for 20 years, and are grateful for God’s blessing them with four children.


Compassionate Care Team – Mozambique

Dara Vanden Bosch, Compassionate Care Coordinator

As a nurse with a background in hospice and palliative care, Dara has seen a huge need in Mozambique to provide this type of specialized care. Many people live too far from a health care setting to even access basic health care services. When someone has a terminal disease or is suffering from pain or any type of debilitation, they may only know a life of suffering. By using a team of trained locals, palliative care is being brought to areas which otherwise would be living with no health care options. The team addresses social, physical, spiritual and psychological issues with a heavy emphasis of using audio Scripture materials to bring the hope and healing of the gospel to those nearing the end of life.


Rabeca J, Compassionate Care Worker 

Rabeca J. co-founded the Mvura Ya Upenhu Palliative Care (what we call the “Compassionate Care”) program in Mozambique with Dara Vanden Bosch. Rabeca has always had a heart to care for the less fortunate in her community.

Even in her free time you’ll often find Rabeca visiting widows, the sick, or even delivering babies! Rabeca often cares for children in need by taking them into her home and treating them as if they were her own. Rabeca, like many of us, has difficulty understanding why so many people experience such suffering. Yet, her favorite Bible verse is a constant reminder that God knows us, forms us, and loves us. Jeremiah 1:5—“Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations” (NIV). Her joy is one of the wonderful qualities Rabeca brings to each patient visit—and the ability to make everyone laugh. For enjoyment, she loves to sing, read and study her Bible, and sew or crochet.


Mariana R, Compassionate Care Worker 

Mariana has been part of the Mozambique Compassionate Care Team since 2015. Most often, you hear Mariana before you see her — her laughter usually goes before her. Mariana radiates joy in everything she does. Her smile and laughter are contagious, which is exactly why she excels at bringing hope to the patients in Mozambique. If you’re driving down rural dirt roads in central Mozambique, you might find Mariana leading the Compassionate Care Team on her motorbike — Mariana is a trailblazer as she faithfully cares for the patients that the team serves.

In her off time, Mariana may be found accompanying those from church, or complete strangers, to the hospital getting them the medical care they need. If not there, she’s providing for her mother and extended family or singing with the youth at her church.

Ann and her husband, Brian, and their two children, live in Zeeland, Michigan where they are involved in a local church. Ann also serves on the Board of Trustees at Zeeland Christian School.


Tom Vanden Berg, Director. Administrative Pastor

Years ago, a Perspectives Course helped him develop a heart for reaching those yet unreached, and he has since spent time overseas serving people at various mission hospitals in Mexico, Honduras, Nicaragua, Kenya, Bangladesh, Afghanistan, and India. Brian resonates with ASM’s passion to reach the unreached with God’s Word in audio, overcoming the challenges of illiteracy and Bible poverty, and partnering with like-minded organizations to connect more people to God’s Word.

Luanne Hoekzema, Director

After graduating from college with a teaching degree, Luanne spent a summer in Utah working with Cambodian refugee children as a part of the Christian Reformed Home Missions.  There she saw firsthand that although there are many cultural differences between people groups, our Savior loves us all with an unending love.  This experience served as a Spiritual awakening for her, even as she served the refugees.  In 2017, after homeschooling and raising 7 children with her husband, she joined an Audio Scripture Ministries mission trip to Mexico through her church. There she witnessed the reactions of the men, women and children hearing the Word of God in their own heart language—and saw how the Bible is truly manna to our soul. She realized how much we take this Bible access for granted, and became convinced of the importance of bringing the Bible in audio for those still waiting to hear.  Luanne has also served on the administrative board at her church, and is very involved in the children’s ministry.  She and her husband live in the Grand Rapids, Michigan area.  Luanne’s life verse comes from Isaiah 41:10: “Fear not, for I am with you, be not dismayed, for I am your God. I will strengthen you, yea, I will help you. I will uphold you with my righteous right hand.”  


John Smith, Director

John Smith* has served on the ASM Board since April 2019. John served for a decade as a language school director and, as part of an international team, provided support to local congregations. He is convinced that bringing the Word of God in an accessible way is a task crucial to reaching people worldwide with the Gospel. John says, “God’s Word is powerful and active, and will bring about the transformation that God wills, for each person, as they hear His Word in their own language.” *John Smith is a pseudonym for this ASM Board member who is ministering in a creative access location.
