Very pleased with their service. It is difficult for us to be without our desktop and they completed repairs in a "timely manner". I highly recommend using DMC if you are having computer problems!

I had DMC build a custom server workstation computer for me. I was super happy with the service, professional advice, speed of responses when I had questions via email, and the final computer far exceeded my expectations! The selection of on hand quality parts and accessories in there showroom was very impressive also and the very knowledgeable sales lady helped me pick the perfect new hard drive to update a older computer. Thanks again DMC for the great computer and service!

I am in business as a software guy. So when I moved to Ludington Michigan I had a lot of concerns that I could not be able to find a store that was able to adequately handle my needs. I tried out a couple locations, but it wasn't until I went to DMC that I found the place that I was looking for. Take it from a guy who is experienced in software, this is the place in Ludington who you want to use! Excellent service. Highly knowledgeable. Competitive prices. Great follow up. Great customer service.

Professional office and staff! I did a little research and did call around for other price quotes and researched parts for my issue and felt the price was a bit higher. I spoke with the tech working on my situation and he declared to me that they do use quality products and they do so to uphold their reputation and I respected that and found their pricing to be reasonable with that factor. I was a little bit bummed because the person I spoke with said although they were not able to read my hard drive that went bad that they could refer me to someone that may be able to with no guarantee.

I went to pick my computer up with a sliver of hope and learned that they already recycled my hard drive. Grant it was a while since I picked up my computer, but figured it would be along with it especially since he mentioned it. Other than that situation I would have given a five star rating. I will still use if needed in the future.
