​Lance Halseth is the Lead Pastor of The Rock Church, which is part of the Calvary Chapel movement. Ronda Halseth is the Women's Ministry Leader.

Lance and his wife, Ronda, were employed with the Knoxville Police Department prior to being called to Haiti. They lived in Haiti while laying the groundwork for Housetops For Haiti, an organization which builds homes and replaces roofs for the families that need them most. As they ministered to the Haitians, they began to learn the local language. During that time several Bible studies were started as Lance taught them through the Bible line by line, verse by verse.

In 2015 Lance and Ronda were called to come back to the States to be a voice for Housetops For Haiti. They moved to Hixson, TN where Lance helped Calvary Chapel Hixson during the week and also started their men’s ministry. While in Hixon, word reached Lance that there was a home fellowship in the Sevierville, TN area that was attended mostly by members of Calvary Knoxville, which is about an hour drive each way. After much prayer, Lance and Ronda were called to move to Sevierville and plant The Rock Church.
