Pros
I have worked at DHTS for almost 10 years and have seen a lot of changes over that time. The biggest shift is the culture of leadership and how they have put a lot of investment in the employees and genuinely care about their well being. It is obvious that this shift started at the top (our CIO) and is further promoted by those under him. They believe in training staff and providing career ladders for growth opportunities, should you choose.
Cons
DHTS tends to sometimes get a bad rap because they are looked at as the first line of defense when something goes down or stops working with the technology. As these mishaps tend to have high visibility, that can create a culture of fear of making and sharing mistakes, which creates a lot of stress in the work environment.
