Our Story at SSE Network Services

SSE is proud to be a woman-owned organization. It all started when Susan S. Elliott, a former IBM programmer, began educating businesses about the importance of technology. Since 1966, we’ve grown to provide some of the best managed services available today.


Why We Do What We Do

The entire upfront process of transitioning to SSE was exceptional compared to the two other firms we worked with in the past. The meticulous way they investigated, researched, tested and really learned how our network supports the daily operations of our business before they ever touched anything was tremendous.

Joe Bayer Jr., Vice President
Creative Director

SSE has been an outstanding partner; ensuring that our computers and network are available 100% of the time. The Pretecht monitoring product has reduced the personnel time required to support our network and has saved us money.

Mike L., Partner
Financial Services Firm

I just wanted to say a quick thank you for the professional and kind service I receive when I call Pretecht. No matter whom I have worked with; they have always worked to fix my computer problem and been patient and professional in their demeanor.
