Honored to Serve. Inspired to Innovate.

Trusted to Deliver.

At ASI, we believe in our Federal Government and the public servants who promote and preserve our way of life. We steadfastly stand behind those who selflessly provide safety, security, and support at home and abroad.

Now more than ever, our economic future and national security are closely coupled with the ability to manage our federal dollars. We passionately offer thought leadership, creativity, and expertise to further mission results and to steward scarce resources.

From mission needs and requirements through procurement and program execution, “Big A” Acquisition is one of the most powerful, critical, and underutilized levers in the federal government for driving efficiencies and performance. We skillfully employ acquisition program management capabilities, methods, and technologies to address the primary interests of government leaders – managing costs and risks, delivering as promised on time, and driving enduring mission performance.

A legacy of innovative and passionate leadership

By hiring the best and brightest thought leaders from the public and private sectors, we build and evolve our team to meet the challenges of today’s government. Our leaders empower us to provide creative, unexpected, cost-effective solutions that push what is possible and practical in the world of government.
