Mark came on board at what is now Creation Ministries International in 2003 to assist with geological work for TJ (now Journal of Creation) and Creation magazine. He was a part-time speaker until late 2007, and loves sharing with Christians and non-Christians alike his knowledge of geology and the Bible.

John has a keen interest in cosmology and how it applies to the creationist world-view. He has published more than 120 papers in scientific journals and holds two patents.

Dr David Catchpoole has worked as a plant physiologist and science educator, specializing in tropical agriculture and horticulture. Until his mid-20s, David was an ardent evolutionistic atheist, but a personal crisis while working in Indonesia brought him to embrace Christianity.
