Wally and Diane Cassellius

Originally dairy farmers in Wisconsin, the Casselliuses joined WIM in 1985, after a WIM missionary shared at a missions conference where God called them to the mission field. Their six children all grew up on the mission field in Mexico and had many opportunities to participate in ministry. In 2021, the Casselliuses moved to one of the least-evangelized cities in Mexico which is also in the least-evangelized state in Mexico. Their mission is to reach the lost, teach the saved, and send the trained. They are focused on praying to break down strongholds in this area, mentoring younger missionaries, and recording teachings for the radio and their YouTube channel. They also continue to network with churches to send short-term groups with the goal of bringing missionaries to plant churches and houses of prayer.
