Public Opinion Strategies is celebrating the 30th Anniversary of the founding of the firm on May 1st, 1991. We will be posting a series of infographics about our work over the years. The third one can be found here. It’s a fun way to focus on our firm’s history, by showing major events that happened during the time period of each of our four logos. We are proud of our work, and appreciate our many clients over the years. We hope you take a moment to read each infographic.
