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.
Our staff members are the heart and soul of our ministry. They live and work among the Sicangu (She chan goo) Sioux on the Rosebud Indian Reservation and the Oglala Sioux on the Pine Ridge Indian Reservation, 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.
