I have worked with Allison + Partners on quite a few projects for various PR events, including coverage of Great Wolf Lodge, their holiday events, Best Hotel Chains for Pets, and coverage of hotels in the San Diego area.
Staff always seems to communicate quickly, clearly, and have knowledge of their clients. The clients they represent seem to trust Allison + Partners, meaning that as a writer I am able to speak directly to Allison + Partners without worrying they are misrepresenting the client.
I have not had any negative interactions with Allison + Partners. :)
I have worked with hundreds of PR firms in the United States and Allison + Partners has been one of the best.
