We are very happy with the quick turn around to get our ecommerce project completed on time. The assigned project manager was great at communicating our requirements and kept us updated on day to day basis. Much appreciated

Sierra Group truly offers the best price and service. We worked with their team to develop our restaurant website, and the team at Sierra was incredibly helpful throughout the entire process. They helped us create a beautiful and functional website that exceeded our expectations. What impressed us most was their willingness to make numerous small changes to ensure we were completely satisfied with the final result. I really appreciate their excellent work and hospitality. I will definitely return to Sierra Group for future website services. Highly recommended!

I've had the pleasure to work with Sierra IT on a number of projects, from building basic websites to full on web shops. As a one stop shop, they do all aspects from website design, coding, and SEO. Even helped us set up payment processing.

For every project they've worked efficiently and fast paced, and gone above and beyond for every aspect of website design. If anything they are too fast and the customers are the ones that feel slow since we have to take time to finally decide what it is we want!

If anyone is on the fence, get off it and work with these guys. I'd give 10 stars if I could.

We came in contact with them after having dealt with a number of web developers that couldn't deliver upon their promises. Immediately upon our first meeting, we gained confidence in their ability to understand our requirements and then provide a sound technical solution to meet our business objectives.

Sierra Group assisted did an amazing job in pointing out critical issues on our web-platform that could have potentially been very dangerous for our business. After implementing all related changes they also helped us with our PCI Compliance Program. I would recommend Siera IT Group to any merchant who is required to get a higher level of online security.
