“You can stop looking for a website design firm now. After having our site designed by two other firms, Thrive Web Design has proven the "3rd time is a charm rule". Had we known that they were going to make it so easy and the end result so much better we would have never suffered at the hands of those other firms. Their understanding of technology is outstanding, but more importantly, their ability to communicate in understandable English was superb. Thrive completed all changes that we asked for in record time and even suggested things that we had not thought of. Often times they were so fast with changes that they ended up waiting for us to review the site and work down our list of issue. ”
