Society of Indian Missions (SIM) is blessed with a team of dedicated and passionate staff members who serve in various capacities and locations. They are committed to sharing the love of Christ with the Native American people and to supporting the mission and vision of SIM.
Born in Honduras in 1970 to missionary parents, Marc Sankey has a lifelong commitment to spiritual service and leadership. He has held numerous roles in ministry, including pastor, missionary, and educational administrator. Currently, Marc serves as the Staff Pastor for Society of Indian Missions, where he plays a pivotal role in guiding and supporting the organization’s spiritual initiatives.
As the President of Oasis Ministries International, he also furthers short-term missionary efforts globally. Together with his wife, Melodie, Marc continues to impact his community profoundly, offering leadership and nurturing faith through dedicated service.
Our staff members are the heart and soul of our ministry. They live and work among different Native American tribes, building relationships, planting churches, discipling believers, and mentoring leaders. They also engage in various community development projects, such as providing education, health care, food, and clothing. They face many challenges and hardships, but they also experience many joys and blessings. They are faithful and courageous servants of God who need our prayers and support.
