Rex Geissler grew up in Carthage, Illinois, near where Iowa, Illinois and Missouri meet at the Mississippi River. Rex’s home in Carthage was three blocks from where Joseph Smith, the founder of Mormonism, was killed. Rex's love of sports including basketball, golf, cross-country, and football led him to start an annual Easter Basketball Tournament (http://www.greatcommission.com/carthage/) in his hometown, where he played on the High School Basketball Team and was named 1983 Western Illinois Player of the Year and Hancock County MVP. Of course, Geissler's 6'4" frame helped out quite a bit <g>. The Easter Basketball Tournament grew to include a couple hundred male and female players from around the United States, over 300 1-1, 2-2, 3-3, and Mixed Doubles basketball games, Dunk Contest, Road Race, and Banquet with Guest Speaker over the annual two weekend stretch while playing on five different courts from 8AM to 10PM on many days during the tournament's eleven year history. And for Rex, the tournament was instrumental in helping grow his organizational abilities and teaching him the value of loyalty and keeping in touch with friends.

Rex Geissler graduated from Carthage High School as Valedictorian and then attended Illinois State University for four years where he graduated Summa Cum Laude with a 3.91 GPA and Bachelor of Science Degree from the Computer Science program in 1987. Since 1987, Geissler has worked primarily in the software industry for IBM from 1987 to 1993 in Boulder, Colorado, as a consultant programmer from 1993 to 1998 for Walt Disney Studios, Banker's Trust, Edison, Prudential, and AARP, and as a pre-sales software consultant from 1998 to the present day for Sybase, Inc.

Rex Geissler began studying the Bible intensely during the summer of his Junior to Senior year at Illinois State University and thanks to God's grace, committed his life to Christ when he was baptized July 27, 1986. After graduation, Rex moved to Boulder, Colorado where he worked as a programmer for IBM for six years. Geissler moved from Boulder to Los Angeles at the end of 1992 to help support a church in Long Beach by leading Bible studies and aiding in the church administration. Rex began a non-profit Bible & Book Ministry which distributed thousands of Bibles and spiritual books in the mid 1990s to 24 geographical church locations throughout the Los Angeles metropolitan area. This non-profit work became a publishing house named GCI Books, which has published ten books distributing over 11,000 volumes since 1995. GCI Books (http://greatcommission.com) focused primarily on the Bible's history, scientific issues, exegesis, and topical studies. GCI's published works include several different authors and books such as Is There A God? - Questions About Science and the Bible, Reasons For Belief - A Handbook of Christian Evidence, Keeping The Faith - The Early Church and the Apostolic Pattern by John Engler, Daniel - Prophet to the Nations, and The Grass Really Isn't Greener - Unfaithfulness and Restoration to God. Rex authored and published a very detailed overview of baptism, Born of Water. After seven years in Long Beach and after Rex's parents passed away in Illinois during the fall of 1998, Rex relocated his family to Highlands Ranch, Colorado in 1999 where his family currently resides.

Rex met Mount Ararat researcher and explorer B.J. Corbin in 1995 when Corbin was searching for a publisher for his collaborative book, The Explorers Of Ararat. Geissler and Corbin became great friends as they worked together expanding Corbin's initial ideas into the encyclopedic, history book, The Explorers Of Ararat: And the Search for Noah's Ark (http://www.noahsarksearch.com/). Rex published, co-edited, co-authored, and helped coordinate the 21 co-authors to produce this 482-page, 265-photograph book. The book is known as an honest, fair-minded, objective, and hard-working research history, stating both the pro and con for each story and alleged claim.

Rex Geissler began the 501(c)(3) non-profit archaeological research foundation ArcImaging (Archaeological Imaging Research Consortium at http://arcimaging.org) in 1999 after his research and studies for The Explorers Of Ararat book were complete. Geissler has been the ArcImaging President since its inception. B.J. Corbin joined Geissler to start ArcImaging, became the ArcImaging Vice President, and works hand-in-hand with Geissler as the two ArcImaging officers. Geissler has always been interested in man's history, visiting and photographing many biblical archaeology sites and museums throughout Israel, Turkey, Egypt, Sinai, Greece, Italy, England, Spain, France, Germany, China, Taiwan, Singapore, and the United States (http://greatcommission.com).

Mr. Geissler worked with Ataturk University in Erzurum, Turkey during October 2000 to create, type from Turkish into English, and sign the Agreement of Collaboration for archaeological research in Eastern Anatolia (http://www.arcimaging.org/GeisslerRex/GeisslerRex1AI.html). Geissler photographed and posted the 2000 ArcImaging Turkey Photo Album from his extensive ArcImaging Research Expedition. Mr. Geissler coordinated the trip and hosting of the Ataturk University Rector and Dean of Sciences & Arts who are over the Archaeology Department on a visit to ArcImaging's Colorado headquarters, which included many scientific tours and ArcImaging presentations.

For the first time since 1989, the Turkish Embassy announced on October 10, 2001 that an international research group, ArcImaging, received federal permission from the Turkish Government and various Turkish Ministries including the Military and the Ministry of Culture to perform scientific research on Mount Ararat. Rex Geissler and ArcImaging were extremely pleased and grateful to the nation of Turkey and to Ataturk University for their support in this scientific research and for this privilege.

Based on the 2001 ArcImaging permission granted by the Turkish Government entities, Rex Geissler was the Project Coordinator on the 2001 ArcImaging Mount Ararat Research Expedition, which was extremely successful and productive. Mr. Geissler and ArcImaging are grateful to the nation of Turkey and to all Turkish entities for their support in this archaeological research. Geissler and ArcImaging look forward to working together with the nation of Turkey as this scientific research continues over the upcoming years and decades to come and Rex recently signed and notarized a new contract with Ataturk University in May 2006. Both Geissler and Corbin were featured on the 2001 History Channel Documentary, History's Mysteries: The Search For Noah's Ark, which aired nation-wide numerous times on the History Channel.

In numerous Christian churches, Rex has taught Biblical Archaeology classes and Seven Churches of Revelation classes with many archaeological photographs. Rex is also involved with a church bible study group and is on the Board of Directors of the Camp Como Christian Camp (http://www.campcomo.com) where he wrote a database program to help track campers and supporters.

Rex Geissler has a wonderful wife Michele and four fun-loving sons (http://greatcommission.com/family).
