Software Development Review from Tashfeen Khan
We had to get an online social gambling application to be developed and after looking into the market we shortlisted Tecziq Solutions. The best part was there prior knowledge of our industry domain which was very helpful.
They have a nice team and very co-operative and flexible. We found them to be very professional and top notch in terms of communication as well - quite prompt. We loved working with them and they are with us our technical partners.

Dr. Mary Young's Review Sourced from Google
Both my husband and I were using a different hosting site for each of our websites. He moved his first to Altec and found it to be a satisfying experience and suggested I do the same. Given that I'm not very tech savy, Brian handled the whole transition seamlessly making it pretty painless for me. Since the transfer, I have had a couple of minor issues which were self inflicted, and Brian was very responsive and quick to resolve them for me. If you want a reliable and hassle free service I would highly recommend you work with Altec.

Exceptional service, Exceptional knowledge and Exceptional dedication. You will see no less when it comes to the professionalism from the team at Altec design. If you are looking for inside knowledge on how your web traffic is performing as well as receiving honest answers with a breakdown of what all the reporting is actually saying then look no further than Brian and Sam at Altec Design St. Louis. We have used them with the Lou Fusz Automotive Network for years and have experienced no less than A+ service. Once you talk with them you understand right away why Altec Design will be the solution to all your companies web related needs.

Altec Design made us feel well taken care of all along the process of building our website. From keeping us on track with their project management, to handling all of the coding and technical aspects of hosting, reporting, adding the widgets we needed to fulfill all of our needs, and their expert advise. It was just comfortable knowing they had our backs! We are so glad to have worked with such a professional team and we are very proud of the website we created together.

We chose PNMG to develop our website in 2018 and have been with them ever since! They are very conscientious of their work and the quality of the employees are top notch, not to mention the great support they add. We have monthly meetings to keep everything current and are very pleased we chose them to partner with!

Our organization hired Vivid Sites to develop our website and custom CMS several years ago. Since then, their service has been professional, accommodating and highly-responsive. It has truly been a pleasure to work with Dave Black and the entire Vivid Sites team.
