Matthew Ellison

Matthew Ellison

President / Church Missions Coach

Matthew was rescued by Jesus when he was twenty-three. Shortly after, he found himself in Ghana, West Africa on the first of what would be many ventures to the mission field. That first trip, he says, “ruined me for anything less than a life lived for God’s global purpose.” In 1993 he began serving at Calvary of Albuquerque, New Mexico, where he attended and graduated from their School of Ministry. He worked as the Missions Pastor at Calvary for nine years, developing and launching a strategic church-wide missions ministry. There he founded an international short-term mission ministry called LifeLine Missions that gave thousands across the country the opportunity to experience the mission field firsthand.

Through these ministry opportunities he became extensively involved in short and long-term mission endeavors around the world. Now, he devotes his time to serving local churches across the country by coaching them in strategically focused missions and helping them to discover and use their unique gifts in partnership with others to make Christ known among all nations. He currently lives in Albuquerque, New Mexico with his wife, Renee.

Rachel Vanegas

Rachel Vanegas

Executive Assistant

Rachel was saved at a young age and grew up in a mission-minded church where she was encouraged to participate in multiple aspects of ministry. She spent much of her childhood and teenage years participating in both domestic and international missions initiatives, cultivating in her a heart for the unreached.

Rachel worked in healthcare administration for 15 years before transitioning into vocational ministry. She spent 4 years with GFM Ministries serving as Manager of Finance and Administration. During her time with GFM, she also helped organize many mission trips and events while learning the interworkings of how a ministry is run.  Rachel is excited to join Sixteen:Fifteen and support the team as they mobilize churches to bring the Gospel to the nations.
Randi Fannon

Randi Fannon

Special Events Coordinator

Randi is a stay-at-home mom who has felt a clear calling to the nations on her life from a young age. While pursuit of that call looked like short term mission through middle school, high school and college, in adulthood, she has found purpose and joy in serving with mobilization ministries at home to see the gospel go out to the ends of the earth.

Randi is the quintessential extrovert and treasures the opportunity to turn off the ‘mom brain’ and love and serve others as part of the 16:15 team. Whether she’s at home with her husband and 3 boys or at the laptop working on details for the next Mobilized Church Workshop, the job requirements really remain the same: someone needs a reminder about where they’re supposed to be and everyone needs a snack.

Lauren Palmer

Lauren Palmer

Director of Communications

Lauren grew up in a missions-minded family, attending dozens of missions trainings and participating in short-term trips to Russia, Israel, and Mongolia before age 12. As a teenager, she had opportunities to merge her heart for the nations with video editing skills, volunteering with several missions organizations. By the end of her senior year, Lauren felt a clear calling to be involved in missions mobilization. 

Prior to joining 16:15, Lauren’s work in mobilization was primarily through the local church. She has coordinated Perspectives classes and served on multiple coordinating teams. For ten years, Lauren was on staff at First Methodist Carrollton, Texas, serving as the Communications Director and Missions Pastor. Lauren holds an MA in Theological Studies (Dallas Baptist University) and an MA in Mission (University of Manchester), and she loves helping Christians find their places in the Great Commission.

Denny currently has served in many church staff roles as worship, missions, and small group pastor and understands the significance of missions in the local church. During his vocational ministry, Denny served on the staff of two mega-churches, directed a para-church ministry, and helped plant several churches. He previously served as VP of Church Partnerships at Pioneers for the past 12 years.

Denny has co-authored the book “When Everything is Missions”  and “Conversations on When Everything Is Missions” with Matthew and now serves with Sixteen:Fifteen through a partnership with Pioneers as a Church & Agency Coach.

Stephen Irwin

Stephen Irwin

Videographer / Video Producer

Stephen spent 17 years overseas in Scotland and Spain in both church planting and creative access media roles. Halfway through that time he met and married Kelly who was working on a church planting team in Spain. He has a special interest in disciple-making and church planting in the Middle East and North Africa.

Stephen sees his video production role with Sixteen:Fifteen as a continuation of his desire to see the worship of Jesus multiplied by encouraging US churches in their missions visions. He’s thankful he can assist Sixteen:Fifteen as they coach churches in fulfilling their calling by sending missionaries to the hardest places.

Stephen and Kelly have two young daughters who were born in Spain. Kelly homeschools them when they are not creating shows and dances for family viewing. The Irwins live in Richmond, Virginia.
