HOME>>ABOUT US>>Testimonials


We have been working with Dennis and the TNI staff since 2004. Our network then was in the stone age. Dennis came in and helped us see the benefit of having a current and sound computer network. That lasted until late 2010 when we moved to a brand new facility and decided it was time for some new stuff. Dennis and his staff setup and got our whole new network working along with a brand new state of the art phone system in a matter of a few days. They have done a great job taking care of us and will continue to do so.

Leading heavy equipment provider to waste and recycling markets

We have been customers of Totally Networked (Dennis Cosmann) for over 10 years. We were referred to him by others we trust in our industry who have been (and remain) his clients for even longer.

We have found Dennis to be professional and knowledgeable in all the technical areas in which we need his expertise. Problems are diagnosed and resolved quickly. More importantly solutions and architecture are implemented which minimize problems occurring in the firstplace. Pricing is fair and more than appropriate for the services provided. In addition to all of the above, Dennis is a righteous person who takes pride in his work; the end result is indicative of that. We recommend him very highly.

We have been using Totally Networked and Dennis Cosmann for 4 years as our outsourced IT Department. Over that time, we have found them to be an invaluable partner in making sure that our firm’s computers and network are up 24/7. They’re responsive, value priced and their team is exceptionally helpful.

I have known Dennis Cosmann and his company Totally Networked, Inc. since the early 1990’s when we hired him to install and manage a very large network for a pre public high tech company. Since that time I have steered both colleagues and clients to his company and have never had anything but extremely positive feedback. Dennis is both personal and professional and can communicate very complicated ideas and solutions to non-technical folks, such as myself, which is refreshing in this rapidly changing “connected” environment.

General Manager

Leading Acoustics Engineering Firm

Before I joined Clearwell Systems as the Director of IT, Totally networked had already made their mark on the company. Taking a start-up company and building its infrastructure and managing all of the IT needs from desktop machines to phones. Doing so that scaling was easy for me to do as the company grew. After I joined I was so impressed with what TNI had accomplished to date I continued using their services in many aspects, most importantly trusting them with the building and shipping appliances to our customers. I have TNI to be a great source for answers and procurement of equipment and software matching or beating the big name retailers out there. What really makes TNI stand out with procurement is the time it takes for me to get my products, half or less the time from anyone else. TNI has played a large part in the success of Clearwell. If and when I move on from Clearwell I will be taking TNI with me.

Clearwell was recently acquired by Symantec, and Symantec continues to use TNI in the same capacity

Major Construction Company

We began working with Totally Networked back in early 2006, shortly after launching our company. We needed a reliable firm to be on call for any IT issues that would come up and fortunately got a referral to Dennis. He was quickly able to assess our environment and matched up one of his senior staff, Raj Suri, to be the point of contact for our firm. Nearly 5 years later, we are still working with Totally Networked and Raj is still assigned to our account. This continuity is extremely important and we are very appreciative of the work this firm has done for us. Raj and Dennis are always accessible and get back to us quickly if we have systems issues. We are happy to be a reference anytime.
