I am not a "heavy user" of Core Group services, being a small LLC, but in each case when I have had a question or an issue, . they have been "on it" (as my Dad used to say, "Like a duck on a June bug"). The best moment was when I was tagged with ransomware, and TCG got 99% of my stuff back in three days, without my having to pay zippo. You will like them!

Great employees, terrible management, HR, and persons in authority. Low pay, horrible environment, egg shells all employees.

Great company! They are a top class IT company - they care about their clients. They take the time to develop relationships and determine what your needs/wants are and build out a solution for you. They don't sell you a bunch of things you don't need - it really is tailored for the environment.
