NSI IT assessment


"As a nonprofit company focusing on behavioral health and educational services for at-risk youth we have seen our services have expand greatly. Even more so has been the growth on our reliance of the ever expanding world of Information Technology. Having gone through many companies and different IT solutions, NSI was the perfect remedy for an ever dizzying array of choices.

Their Total Care product is exactly what was needed. NSI provides us with a virtual IT department at a fraction of the cost including on-site support for our over 250 employees, strategic management of services, procuring products and troubleshooting problems. Best of all, their Total Care product takes the discussion of whether something is ‘in scope or out of scope’ off the table. Together with NSI we function as a real team aimed at getting the job done!"
