    Tier Tech International


Tier Tech International was established in Virginia Beach, Virginia in 2003.  Its founder, Walter Houston, clearly recognized our Nation’s need for a business that specialized in cutting-edge tools, techniques, and procedures to counter evolving Weapons of Mass Destruction and Improvised Explosive Device threats on both the domestic and international fronts.

In the early years, TTI developed its reputation for superior products and excellent customer service by providing training and consulting services to wide variety of clients, including the Federal Bureau of Investigation, Department of Homeland Security and the National Laboratories.  The majority of TTI’s work was focused on analyzing national capabilities related to countering terrorists’ use of Weapons of Mass Destruction, identifying capability gaps, and shaping effective solutions for Federal, State, local, and private sector entities.

In 2007, TTI relocated its headquarters to McLean, Virginia.

Tier Tech International’s corporate capabilities have steadily increased since 2003.  Our executive staff and field operations teams include senior policymakers and professional counterterrorism experts.  Currently, TTI’s staff are located in six states and the District of Columbia.  TTI has onsite personnel at the Social Security Administration, Idaho National Laboratory, Ft. Bragg, scientific and public health expertise in the Republic of Korea, and a team of state and local anti/counterterrorism experts conducting capability analyses, nodal opportunity analyses and multijurisdiction exercises throughout the United States.

Last year was a year of unprecedented growth for the Company and we have similar expectations for this year and beyond.

Tier Tech International remains committed to strengthening our Nation’s security and making the world a safer place.


Tier Tech International remains committed to forging productive, long-term relationships with our clients by providing thought leadership, innovative solutions, superior products and services with unsurpassed loyalty and customer service.


Tier Tech International was founded on the principles of integrity and commitment to superior performance while providing cost-effective solutions to clients at home and abroad.
