entX is pleased to welcome Dr. Brett Seidle as a Non-Executive Director on the entX Board.
Dr. Seidle brings more than 25 years of experience across the US Navy's research, development, engineering and acquisition enterprise, including senior leadership roles spanning advanced R&D, prototyping, experimentation, test and evaluation.
His executive roles included performing the duties of the Under Secretary of the Navy, Acting Assistant Secretary of the Navy for Research, Development & Acquisition, Executive Director of the NAVSEA Warfare Centers, and Technical Director at NSWC Crane.
His extensive experience across defence, advanced technology and large-scale engineering organisations will be highly valuable as entX continues to build its presence in the US Space and Defence markets.
