Barry Wissler is the founding president of HarvestNet International (HNI), a network of churches, ministries, and businesses partnering for the harvest. Barry and his wife Cheryl have been in ministry together for 45 years. Having founded and pastored Ephrata Community Church for 37 years, Barry passed leadership to a successor and now devotes his time to HNI. Before pastoring, Barry ran a family farm with his father and also did some real estate development. Barry’s paradigm for harvest comes from his time farming with his father. Barry, his father, and his uncles always partnered together to bring in the harvest on each farm.

Today, he works to build teams and equip leaders to do the same as God’s family and in God’s harvest. He leads a team of staff and international leaders to network and equip frontline workers for world harvest. Under his leadership, HNI established Gateway House of Prayer, a 24/7 regional prayer center; and HarvestNet School of Ministry, which equips the saints to fulfill their calling. Having written several books, Barry holds theological degrees from Geneva College and Westminster Theological Seminary, as well as a Doctorate of Ministry from the United Theological Seminary.
