My name is Caitlin Emfinger Rosa. I have been serving in Brazil for four years, one year alongside my husband Arthur. When I was 16 years old, the Lord called me to missions. Since then, I have been on various mission trips and spent three years as a Missionary Associate to unreached people groups with Joil and Leah Marbut in Ecuador before God led me to Brazil. I worked for 2 years in São Paulo and currently am based in Nova Iguaçu, Rio de Janeiro. 

Arthur has been part of King's Castle since 2019. He is originally from São Paulo, Brazil. He graduated from IMPACT-UC (King's Castle School of Missions) in July 2022. We met in 2020 while I was working at IMPACT as an English tutor. We married in December 2022 and have been serving together since then.

My husband and I work with a ministry called King’s Castle. King's Castle is a ministry focused on teaching children the gospel and training leaders to reach children worldwide. King's Castle is currently in dozens of countries all over the world. Our passion is to see young people on fire for reaching the world for Jesus Christ. 

I work in the area of communications. As a photographer for nearly 20 years, my job is to capture what God is doing in Brazil. I also help with videos and content creation for King's Castle Brazil's social media pages. Arthur is the administrative assistant for IMPACT-UC, a ministry school for young adults who feel a call to missions. He also works in the areas of evangelism and discipleship. Together, we direct a weekly children's service in a local neighborhood. In this service, we get to disciple young kids who have little to no contact with the church. We are also both English tutors for IMPACT.

Our heart desires to stay on the mission field as long as the Lord allows, wherever that may be.
