I wanted to take a few moments to provide positive feedback on one of your employees. I have been working with Alexandria Leslie on some very challenging and tough requirements within the Remedy Smart Reporting Tool. I have been very impressed with how responsive she has been and her willingness to put fourth her very best effort to craft solutions that really tested the reporting capability of the tool. Her attention to detail and hard work is to be noted. We in SE6 really appreciated the work that Alexandria does to support our requirements and look forward to working with her on other reports that serve to assist Leadership make critical decisions regarding funding and resources. Her efforts are truly appreciated.


I wanted to send a note expressing my gratitude to you and your N6 team for getting back up and running so quickly. Alfred, specifically, ensured everything went smoothly. It seemed as if there was a problem, my computer had it! After a new computer and successful transfer of my emails and documents, I am up and running! Thanks again for the support!​


I just wanted to write to give a "that a boy" to Matt Jones. As we are all aware, the ISD transition has been quite a task. We still have a lot of work left but we are making progress. I would like to note that Matt has gone above and beyond in assisting with the move. Anytime I have asked him for any help he has been willing with a positive attitude. I just wanted to make sure his company is aware the government on site couldn't be happier with the support he has provided in this endeavor.
