From 2005-2013, Naomi was head of communications for the Lausanne Movement. The 10 years prior to that she led communications for the U.S. Lausanne Movement (Mission America Coalition).

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 had a background 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.

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.

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 early on in the year 2015. Sarah and her husband Patrick have 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  

Lloyd is a retired pastor. In the 1970s, he was introduced to Dr. Ronald Beery, the founder of ASM, by his father, Edward Wolters, who was Ron’s colleague at Hope College. Edward was impressed by what Ron was doing to help missionaries spread God’s Word by providing “timely technology for the timeless Truth.”  Ever since, Lloyd has tried to lift eyes to the harvest of non-readers in the world who are ready and eager to listen to the voice of the Good Shepherd. He emails churches and individuals about ASM’s work, also inviting groups in West Michigan to come to visit us. Lloyd owns a complete replica set of Aaron’s garments, as designed by God and recorded by Moses in Exodus 28. He presents this preview of our Great High Priest, Jesus Christ, for no charge, but he does require permission to do a “commercial” for ASM. Another of Lloyd’s hobbies is beautifying the yard around his home. Still another hobby is playing his trombone with the Grace Gospel Band. The band visits retirement and nursing homes on Monday evenings and gives all of its honorariums to ASM.

Don Lang, ASM Representative  

Don Lang has walked with the Lord most of his life.  He graduated as an Electrical Engineer from Oregon State University and worked for Electric Utility Companies for 40 years.  Don had been married for 28 years when his wife unexpectedly passed away due to a heart attack in 2010.  This event marked the beginning for him of a renewed and enhanced spiritual walk as he allowed the Lord to navigate for him through this most difficult season.  Don has a son and daughter who experienced the same amazing love the Lord can offer.  Don’s testimony and story is an example of God’s restoration, unerring leading, infinite compassion and unconditional love.  When Don experienced one of life’s most difficult challenges, the Lord strengthened his faith and showed him the best of times are still ahead.

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.

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.

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  

Joachim Domingos, Recording Technician  

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.

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.
