At Grindstone Ministries, we take the safety, effectiveness, and integrity of our mission seriously. That’s why all volunteers must complete a pre-approval and vetting process before deployment. Once approved, you'll receive deployment specific opportunities and instructions directly from our team. Please do not self-deploy, only those who have completed the volunteer application and been approved will be invited to serve on the ground. This process ensures that each mission is carried out with excellence, coordination, and care.
