Client Testimonials

  • "I would like to extend our thanks for the excellent job FEDSIM did for the CDM program. We feel confident that the winning bidder has a strong understanding and appreciation for the program's importance, its innovative nature, and the challenges we will face during implementation. The innovative source selection structure was key to the award’s success, and today’s kick-off meeting validated the utility of the approach. In addition, your dedication, commitment and comprehensiveness was highly valued by your team at DHS."

    - John Simms, CISSP, PMP, U.S. Department of Homeland Security

  • "I wanted to take a minute to let you know how pleased I am with the support we’re receiving from AAS FEDSIM. As you are aware, SEC has done business with AAS FEDSIM on several engagements and the recent support we’ve received to de-obligate unneeded funds has been excellent and worth noting. We look forward to the second deobligation being awarded, but in the interim I wanted you both to know how much we appreciate the hard work and that FEDSIM's work will make a difference for us."

    - Vance Cathell, Director of the Office of Acquisitions and Senior Procurement Executive for the SEC

  • "I spent the past two weeks at GSA working with your FEDSIM personnel. It was truly a pleasure to work with such a highly qualified and dedicated team of professionals. FEDSIM has exceeded my high expectations for assistance; developing the very complex requirements and successfully awarding the global Task Order.  The GSA OASIS is the best acquisition method for what my organization requires and is fulfilling a requirement which otherwise would not be met.  Thank you for your support on this extremely critical mission to support the Army's soldiers!"

    - Theodore C. Kientz, PE, Engineer Division, FORSCOM
