Staff & Board

  • Carol Acosta

    Director, Board Member, FOunder

    Catching a glimpse of the greatness and glory of God, Carol has been "wrecked" by the vision of Revelation 7:9 where people from every nation, tribe, people, and language encircle the Throne shouting praise and worship to the Lamb. Her greatest desire is to be a faithful messenger of the message of reconciliation and to be used to get that message to the ends of the earth. She loves being with her hubby and son watching a season of NCIS, reading in bed, praying with her prayer group, and getting together with extended family for a rousing round of Mexican train. For questions or comments, email Carol.

  • enrique Acosta

    Director/Board Member ex-oficio on health sabbatical

    A Texan by birth and a Longhorns fan by genetics, Enrique's heart is wherever there are people who need to know about Jesus. Evangelism and missions (and baseball) are what flips his trigger, but he's also a committed husband to Carol and a doting father to Gabriel. Having been transferred from the kingdom of darkness into the Kingdom of Light in his mid 20's, he delights to share how great Jesus is and how able He is to rescue the lost.

    Though officially retired, Jerry continues to use his medical knowledge and generous heart to minister in various ways. He and his wife, Marilyn, have served on the board for more than 20 years and have taken various trips with RBW. He loves to travel and can communicate somewhat in more than 15 languages - always with the goal of showing Jesus to those he comes in contact with. 

  • Marilyn Kiedrowski

    Along with her husband, Marilyn's heart for the Lord Jesus comes out in a lifestyle of service. Talented with computer skills, organization, creativity, and boldness, she blesses people in Jesus' name wherever she goes.

  • Teresa Naser

    Board Member

    Teresa was bit by the missions bug in January 2015 and it has since become her passion. She has been studying Spanish for over three years and spent three weeks in Guatemala learning in an immersion school. Teresa has had the opportunity to translate and help lead teams in Mexico. She gives her all and isn’t afraid to step outside her comfort zone, giving her the chance to totally trust in the Lord. She has a servant’s heart and is looking forward to being involved in the ministry work in Nicaragua or wherever else the Lord leads. Teresa, her husband Trent and their two daughters are from McClusky, North Dakota.

  • Trent Naser

    Board Member

    Trent started missions work in 2015 after his wife and oldest daughter returned from their first trip in Mexico and insisted the whole family go again. He has since been a part of seven different teams. Not only does he enjoy sharing about Jesus, but he also likes to use his many skills to benefit others: construction, leadership, carpentry, painting and more. He is excited to continue serving through RBW Missions and is looking forward to new experiences in Nicaragua and expanding his Spanish vocabulary. Trent, his wife Teresa and their two daughters are from McClusky, North Dakota.
