I just wanted to say thank you for the great support that SIS gives us on a weekly. Case in point, we had a significant virus issue the week our IT Manager was on vacation. Without the dedicated work of the SIS team the day it happened, we would have had a VERY serious interruption of our business!
Thanks for all of your support and for your expertise in working us through our challenges and our routine projects.
