Board of Directors

  • Roland Angle graduated from the University of California, Berkeley with a Bachelor of Science in civil engineering, served in the U.S. Army Special Forces, where he was trained in the use of explosives, and became a licensed civil engineer in California. His fifty years of engineering experience has included designing and testing blast-hardened missile launch facilities and designing U.S. Naval explosive containers, harbor terminal facilities, earth foundation systems, and hydraulic systems.

    In addition, Angle has owned three construction companies and has taught engineering subjects to high school students. He was skeptical of the official explanation for the failure of the World Trade Center towers but did not investigate in depth until he heard a presentation on the radio by AE911Truth founder Richard Gage several years after the attack. After doing further research, he signed the AE911Truth petition and began to devote long hours to uncovering the truth about the events of 9/11.

    In 2016, Angle was invited to join the board. He became its chairman and the non-profit's chief executive officer in October 2021.

  • Larry Cooper received a degree in civil engineering from the University of Wisconsin in 1967 and a Master’s in structural engineering from the University of Illinois in 1970. As a Registered Professional and Structural Engineer in several states during his nearly fifty-year career in consulting engineering, he was involved in designing, constructing, and inspecting bridges, wastewater treatment facilities, and industrial structures as well as managing structural design and transportation engineering groups.

    He was also active in the American Society of Civil Engineers and the American Council of Engineering Companies. Cooper is a member of the ASCE and the Structural Engineers Association of Michigan.

    He first became aware of Architects & Engineers for 9/11 Truth in 2013. After viewing a video of the collapse of Building 7, which he saw resembled a controlled demolition, he immediately signed our petition. Five years later, Cooper gave his first presentation on the collapse of the World Trade Center buildings. In mid-2018, he began serving on AE911Truth’s Project Due Diligence Committee. And in November 2021 he joined our Board of Directors.

  • Tom Spellman has an undergraduate degree in architecture (with a minor in civil engineering) from the University of Wisconsin–Milwaukee. He managed a housing co-op for fifteen years and was an accountant for five years.

    In late 2002, he learned that the official story of the World Trade Center’s destruction could not be true. Upon hearing Dr. Steven Jones state that random fires and damage could not produce a symmetrical collapse, Spellman understood that explosives had to be involved.

    Later he contacted AE911Truth founder Richard Gage to clarify technical points made during a presentation and was invited to join the weekly team calls as a volunteer. He has served as treasurer of the Board of Directors ever since.

  • Kamal Obeid holds a Masters Degree in civil engineering from the University of California, Berkeley. He has been a practicing civil and structural engineer in the San Francisco Bay Area since 1980 and a licensed structural engineer since 1985.

    During his career, Obeid has served as engineer of record on many building design and retrofit projects. He specializes in structural steel building analysis as well as investigating structural failures of steel-framed buildings.

    At one point he served as a volunteer for the Office of Emergency Services (FEMA), investigating earthquake failures. Obeid is a long-time member of the Structural Engineers Association of Northern California and has served on several of its Code and Business Forum committees.

  • Bill Brinnier has a Bachelor of Architecture degree from Pratt Institute in Brooklyn, New York. Licensed to practice architecture since 1984, he worked with several architecture firms in Manhattan and for thirteen years was director of facilities at a major corporation headquartered in New Jersey. He now presides over a small architecture practice in the Hudson Valley. 

    Bill and his best friend and business partner — Pratt classmate Frank DeMartini — watched the World Trade Center being built in the last three years of its seven-year construction (from 1970 to April 1973, when it opened). As ambitious young architecture students, neither of them suspected that Frank would one day work at the WTC —first for Leslie E. Robinson Associates in the wake of the 1993 bombing, then, starting in 1999, as Manager of Construction for the New York/New Jersey Port Authority. Nor did either of them dream that Frank would be killed on September 11, 2001 (his department occupied the 88thfloor of the North Tower). Because of Frank's connection to the Trade Center, Bill became very familiar with the North and South towers, from their roofs to their sub-basements. 

    After Frank lost his life on 9/11, Bill became active in the quest for an independent investigation into the collapse of the Twin Towers and Building 7. Bill has appeared in several AE911Truth videos. He joined its Board of Directors in 2021.

  • Scott Grainger graduated from Colorado State University with a Bachelor of Science in civil engineering. He served in the U.S. Army at Ft. Huachuca, Arizona, as an enlisted man. 

    Grainger holds a license to practice engineering in several states as a civil engineer and/or a fire protection engineer. After practicing engineering as a construction project manager in the private sector and after acting as a resident engineer for the U.S. Army Corps of Engineers, he started his own engineering firm, Grainger Consulting. In his firm, he specialized in fire protection engineering, fire and building code consulting, and forensic engineering for 36 years, before semi-retiring in January 2021. 

    An active member of many professional societies and industry organizations through his engineering career, Grainger has also done board-level work for many organizations in support of the engineering profession or related to civic theological responsibilities. One of the first engineers to sign the AE911Truth petition in 2006, he has been supporting the organization in many ways ever since, including joining its board of directors in November 2021.


  • Andy Steele received a Bachelor of Arts degree from the University of South Florida in 2001 — the same year as the event that, unbeknownst to him, would one day compel him to become a full-time activist for truth and justice. In 2004, Steele joined the Peace Corps and served as a teacher and community organizer in Uzbekistan. Some months after returning to the States, he began researching the events of 9/11.

    So deeply was he moved by what he discovered that he decided to become an independent journalist so he could educate others about the World Trade Center evidence.

    In 2010, Steele began to volunteer for AE911Truth and five years later was hired as manager of operations. In that capacity, he coordinates the work of AE911Truth’s volunteers and oversees its day-to-day organizational functions. In addition to his regular duties, Steele hosts the 9/11 Free Fall podcast, an half-hour weekly show that focuses on discussing AE911Truth’s activities and features experts on subjects related to the World Trade Center destruction.

Lead Volunteers

  • Steven Olsen has worked as a software and web developer since graduating with a B.S. in Computer Science from Brigham Young University in 2005.

    During that time he has led numerous teams of various sizes on a wide range of projects for such companies as Ricoh Canada, Trans Plus Corp, and Desire2Learn.

    Steven is delighted to be able to use his skills to help AE911Truth further its mission of educating the public through its online presence. He originally joined AE911Truth’s web team in 2011 and has served as the team’s leader since 2014.

  • Xander presently works as a nuclear medicine technologist, where he uses radionuclides and highly advanced imaging equipment to diagnose and treat various pathologies. He previously worked as a health physicist for the State of Arizona and as a Mammography Quality Standards Act (MQSA) Inspector for the FDA. In the latter capacity, he ensured that medical and industrial registrants were in compliance with regulatory rules and law.

    He’s a member of American MENSA and a published origami author and artist. Xander understood in 2001 that the official explanation for the World Trade Center’s destruction was erroneous, but felt it was far too daunting a topic to face at that time.

    He was inspired to take action in 2011, when he learned of professor Steven Jones’ research and the malicious treatment Jones received. Xander is a member of the foreign signatory verification team, where he helps to determine the authenticity and qualifications of architect and engineer petition signers outside the U.S.
