What Our Clients Say About Our Performance Excellence…
Read what our clients think about us:
”I have never, in my 24 years of Government contracting, experienced such dedicated, persistent, and personal support from a vendor than I have from GDIC.”
“I have never, in my 24 years of Government contracting, experienced such dedicated, persistent, and personal support from a vendor than I have from GDIC. Your team remained in constant contact with us during, and after contract award on OASIS+. Whenever the Government issued an EN to GDG you guys were on top of it, in some cases you notified us prior to the Government. In this industry everything moves at the speed of trust and that is the relationship that we enjoy with GDIC!”
Bob Bevelacqua, Chief Growth Officer, Guardian Defense Group, Inc.

Thanks … I know it was a long few months for all of us, but we got there! Much appreciate all the support, especially all the document tagging toward the end.
Thank you … The GDIC team were great to work with and we appreciate all the guidance and support the team provided. We will be sure to reach out should we decide to explore more in the future.
On behalf of J P Systems, I also would like to thank you all for your time, effort, and assistance that has enabled our team to successfully complete our WOSB M&A submission!
Again, thanks for the guidance. I appreciate the complexity of this proposal, and your surgical precision in auditing and keeping abreast of myriad gov last-minute changes, so we could get to the proposal submission.
You and your team did an exceptional job getting us across the finish line. It is not how you start that counts but how you finish. GDIC finished strong. Until we find another opportunity to work together – Take care.
We greatly appreciate the support we received from GDIC… (the proposal manager) provided us with timely, up-to-date information and advice crucial to our bid package submission … Thanks again!
