Rhosel Dayrit Practice Administrator at Neurospine Institute Medical Group
5.0★
IT Services Review from Rhosel Dayrit
My top 3 things about TruAdvantage:1) The single biggest benefit is Security. Since we are a medical field office, our primary concern is securing patient’s files and account information. Second would be backup. Since most of our work is online it is important to have back up on all files electronic and non-electronic.2) Customer service is excellent and dealing with our issue at a moment’s notice is beyond expectation.3) I would highly recommend for them to try it out. they will see a big difference in the proficiency of work, the team itself and the care to their customer’s need.

Managed Services Review from Girish Rochwani
During all our dealings with Advanced Networks, we found them to be an incredibly supportive technology partner. At all times their staff exhibited an excellent level of technical ability, a clear focus on our specific needs, and an anticipatory approach to our IT requirements. Each of the engagements that we agreed on was completed on schedule and they were always ready and willing to assist with additional support and/or consultative services. We also appreciated their balance of covering all bases with regard to the reliability and security of the solutions they provided with the requisite scalability. Their staff made the entire engagement process very easy and their level of service was unparalleled. For all the above reasons, we have no hesitations in recommending Advanced Networks to all corporations that require a dependable and competent managed IT service provider that will also cover their ongoing IT support needs.

InlineAdam's Review Sourced from Google
So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.
