PRSSA's website used to have an info page on each chapter listing its president, faculty adviser, professional adviser, etc. But that was not a comprehensive list of all contacts in one place. And it doesn't look like the site has that feature anymore. Now it's just a list of chapters with links to the chapter's website, and many chapters' listing doesn't even have a link.
