Meet the Presenters

Our presenters will help you to reimagine what community engagement can look like by introducing new technologies, social service events, community networking tools, as well as traditional and progressive evangelistic methods. With seminars and workshops on church growth and evangelism, we will leave you with a ministry toolkit for God to move your congregation from the sideline to the front-line of Kingdom growth using communication and cutting edge resources for ministry, leadership, and Biblical teachings presented by experts who are not just reading about it, but living it in daily ministry.
