You can't go wrong with SD Tech. I am a retired Network Systems Engineer working for S & P 500 global corporation in IT, and have worked with hundreds of Computer Technicians over my career. There are many with lower skill levels and/or attitude problems - you may have met some. This is the cream of the crop! Extremely impressed with SD Tech, they are skilled, timely, professional and spot on. Pricing is also great. This is a real review from a real customer. if you need technical, computer, phone, Internet, Microsoft, home or business automation or web cams, try them!

After years of having my business email hosted by another company I started having issues receiving emails from people. I called SD Tech to help me fix it and within the day they had everything up and running. I'm switching all my hosting over to SD Tech. They have reasonable rates and great service.

I can't say enough about Wes and his team. I was reluctant at first but then I realized that for my companies to grow, I need his team to upgrade all of our phones and systems to something more professional and reliable. He delivered and it's comforting to know that I have an IT team at my fingertips

I needed a laptop worked on and did my research and chose Sd tech. I called in the morning and by that afternoon it was up and running and Wes shared some valuable tips on how to keep my PC working at maximum efficiency. Don't call the geeks, call SD tech!

Wes Ulmer is always responsive to my computer needs. He has built two of my computers and therefore more efficiently can update them. This saves cost and having to get rid of a computer just because it is outdated. I trust that Wes will provide me the best product, the best service for the best price in a timely way. My business is hiring SD-Tech to revitalize our website.

He understands what it takes to get our name to the places on the web that will benefit our business. I can't imagine using anyone else. Wes's customer service is outstanding!

It has been a great experience to engage SD Tech for my office computer networking system. They designed and installed a replacement for my old system and it has enhanced our productivity. The technicians have been completely professional, courteous, and dedicated to assuring system integrity and reliability. I highly recommend SD Tech.

When I contacted SD Tech to do some work for us at our factory we were working with several different computer techs and programmers. It became very clear, very quickly that SD Tech's service and competency level was head and shoulders above the rest. They quickly pointed out some of the problems we were having, antiquated equipment that was in a state of disarray, programs that were not working properly, several machines that were affected by ad-ware and a server that was failing.

They gave us a comprehensive plan to repair and update our equipment.

SD Tech worked with me throughout the entire process, explaining what they were doing (in a manner that a layman could grasp). They built a new server, connected two new Vista machines to the network, went through all of our machines (approximately 17) making the necessary repairs or modifications to ensure that we would have reliable machines that we could depend on.

They also set up user groups and permission levels on our network to give us some organization and structure. As anyone who has gone through this process can tell you this can be very frustrating, but SD Tech managed to complete the task in a timely manner and worked with the entire organization to make this as painless as possible. They recognized the priorities at hand and accommodated the staff to keep us all working during this difficult time.

Once the system was in place he continued to work with all of us to ensure that each workstation functioned properly, basically customizing them for each employee's job requirements. Now that this process is completed the cries that my computer doesn't work, or my machine is slow are silenced. With the system we have in place I am able to maintain our network, perform simple changes necessary to keep us moving forward all while reducing our dependency on so-called computer techs.

Wes Ulmer and the employees of SD-Tech have been working with us for approximately 4 years. They are responsive to inquiries, quick to respond to issues and never make me feel like they are talking techie to me. I call with both easy and complex issues and they are always ready to help.
Amy Miller, Owner
SD Tech has been assisting us with our computer needs for the past 2 years. I love working with Wes and his company because they are quick to respond to our technical problems and are able to deal with any type of issue that might arise. They provide excellent customer service and are willing to go the extra mile to help us! We have developed a great relationship with this company and will continue to use their services and refer our friends for many years to come!
