Public relations professionals are often accused of "spinning" a story, or stretching the truth. If you believe in stereotypes, the average public relations professional is someone who is trying to sell the public on half-truths to make the big bucks.
At Mack Communications, at least, this is far from how public relations works. The goal of public relations is to help individuals, companies, and officials tell their story. Many companies don't know how to do this best, or how to explain their work to the public in an clear way. Public relations uses "spin" to tell a client's side of the story.
