As a company that distributes food items across Canada and the US, it is critical that we have fast, reliable computer systems that can operate 24/7. In addition it is essential that we have access to immediate remote trouble shooting and on-site service from our IT resource supplier. All aspects of our distribution system from purchasing, payables, sales, receivables, and statistical data are reliant on our computer system. A computer crash for us means that we are essentially out of business until the problem can be rectified and what makes the task even more difficult is that we have 6 Servers and 46 workstations which 16 of them are constantly out of the office and across Canada and the U.S. but Diagnostic can access the systems and correct the problem no matter where they are located.

Diagnostic Network Technologies has provided this service to us since 1997. Diagnostic has always been there when needed and has successfully seen us through several crises over the years. Their staff from the President on down has always been courteous and extremely knowledgeable and has treated Olympic throughout the  years as priority No.1 ( or at least one of their priority No. 1 customers).

I can unequivocally state that I would highly recommend Diagnostic Network Technologies to anyone looking for a company to provide computer support whether it be software or hardware.

We are a boutique consultancy that is project oriented, with all our work being driven by time-sensitive deliverables. Diagnostic Network Technologies has supported our business since we opened over 12 years ago, and prior to that DNT had provided the IT support to the regional office within which I was a partner. Leo and his team have kept our systems up and running, and with the latest remote monitoring software they have been able to make software updates, adjust settings, and identify hardware weaknesses without having to come to our offices and disrupting our schedules. They have always been exceptionally responsive to any problems we have encountered and within minutes have been able to trouble shoot these and identify a solution. Since bringing DNT onboard, we have never had to call a client prior to a deadline and plead systems failure. Leo, thank you to you and your team for the support I have been able to rely on over the past 17 years.

Government Relations and Information Services Publishers of the Ontario Government Information Binder©

 

Leo Stefanidis and his team at Diagnostic Network Technologies have helped my firm since the early 1990s. Our products – the Inside Queen’s Park newsletter, the on-line Ontario Government Information Binder and other publications on provincial government and politics – are time-sensitive and must reach our subscribers without delay.

Whenever GPMRL needed quick service, Leo and company addressed the problem immediately via remote access or an onsite visit. To see the Diagnostic operatives in action is to understand what ‘full-service’ really means. They address even third party problems with outside providers so that we do not have to deal with it.

All of our hardware, software, wiring and the entire setup in general are provided by Diagnostic as they also maintain the lowest pricing in the market since day one.

I’m still grateful to the computer trainer who recommended that we use Diagnostic. They have done us proud over a business relationship which is now headed into its second twenty years.

Thank you, Leo.

Summerhill Market is a boutique grocery operation that is a leader in prepared foods and prides itself on carrying the highest quality of product.  We have been working with Diagnostic since 2014.  Prior to using Diagnostic I was regularly spending hours that I didn’t have trying to maintain my computer.  Our office team was not big enough to have an IT person on staff, and so we would try to troubleshoot computer issues on our own.  Since working with Leo, I have not had any downtime due to computer issues and feel confident that if anything were to happen, that Diagnostic has the backups in place and the ability to get us up and running again very quickly.  Leo and his team are easy to work with and are quick to respond to any issues.  For a business where it is not feasible to hire an IT department, Diagnostic is the way to go.  It is worth every penny and is a huge time saver.  Thanks Leo!

I have known Leo for almost 15 years – from the time I was a partner in a small consulting firm to now, as a sole practitioner in my own company. He and his staff have consistently provided excellent products, services and support. Leo is a firm believer in ‘doing it right’ and his recommendations are always backed up with solid rationale. If you are reviewing options at different price points, you will understand what you are getting (or not) for each option.

When my husband and I moved to Germany in 2007, Leo set me up with a home system that served me well until this winter. When it was apparent that I needed to upgrade, I emailed Leo for his advice and over the course of a week, we determined what I required to best suite my needs. I ordered a new laptop from him and during a short trip to Canada a couple of weeks later, I was able to receive it, fully set-up and customized. Back at my home office, Leo helped me remotely with transferring files, setting up my email, etc. I had absolutely no downtime and the transition was seamless. Since most of my clients are in Canada and I work remotely, this is a top priority for me.

Why do I recommend Leo and Diagnostic Network Technologies?

  • whether you are big or small, every client is an important client
  • excellent response time and problem solving
  • enables/fosters an understanding of what the system can do for you
  • provides excellent support, products and services
