Glen M. Tellis, Ph.D., Professor and Department Chair, US University.

For the past 20 years, I have worked with the team at Online Productivity Solutions. Their work is outstanding. They have created software and websites for several of my textbooks that are used by numerous universities in the United States and internationally. Thousands of students who use the websites everyday have indicated that they are easy to navigate and very intuitive. The ultimate accolade for the work that Online Productivity solutions does is reflected in student feedback. They are the eventual consumers, and it is obvious from their comments that they are extremely satisfied.
