      WordPress Review from Meagan Pate

      Singula Web Development Group redesigned our website from scratch and built it with WordPress. To start off the project, they looked at our site statistics and traffic and talked to stakeholders within our association to find out what our goals were. After that, they went straight to the actual development and design process. During this phase, they worked on our sites backend, adding our requested features that included integrating a management system. They also worked on the color scheme and other design elements.The quality of the website is great and fantastic. Plus, the management system they have integrated works really well. We have also received more traffic to our website since having them redesign it.

      Kegan is a pleasure to work with. Always responds in a timely manner and has great knowledge and insight into web design. He's incredibly reliable and has a great work ethic. He is not into nickel and diming customers (unlike many other companies) and is passionate about what he does. His pricing is incredibly fair and because of his positive approach to work you get an amazing customer experience. I would highly recommend him to anyone looking into web design or on-going web maintenance for your site. He's brilliant!
