It has been nearly 21 years since our company, Koam Engineering Systems Inc., (otherwise known as KES Incorporated, or simply KES) began providing innovative systems engineering solutions to our valued customers in the defense community. From its inception, KES was meant to be a company that provided both efficient and effective service - as well as one that genuinely cared about the success and well-being of both its customers and its employees. Looking back on the last 21 years, I would say that we have lived up to this inspired vision and that we have much for which to be proud. 
 

When KES was founded in 1994 we had but one thing in mind, that our company would do better, that it would strive to provide the best possible service to our customers, and that it would also provide a positive and supportive working environment - one in which our employees would be both happy and productive. I sincerely believe we have achieved this ‘win-win’ scenario...and that we will continue doing so in the future.
