Don’t Take Our Word For It…Here is What Some of Our Clients Have to Say

We selected Theta Marketing after interviews and proposals from 5 other web designers. We liked the fact that Josh came at the web design process from a computer science background with an understanding of the architectural underpinnings of web design. Since web sites have long ceased to be “brochure ware” with limited interaction and have become a primary interactive tool for engaging with clients, constituents, and a host of others, we felt it was key to have someone who understood the inner workings of things like database design and management, interactive blogs, content management software, search engine optimization, and things of that nature. We’re very happy with the response and quality of Theta Marketing’s work.

Theta Marketing is great to work with and easy to get a hold of. They do a good job of getting my issues and requests done in a timely manner. They will even take the time to stop by and show me the changes they have made to my website. I would recommend Theta Marketing to anyone.
