As journalists, brand owners and industry professionals, daily we must interact and engage with communication specialists to accomplish a myriad of goals. Like anything, some individuals tend to be more efficient, trustworthy, effective and more of a pleasure to work with overall.

There is nothing more upsetting than wasting time and money on services that do not meet your company’s needs, especially if it can be avoided. So understanding who these people are can help us in our collective decision making when it comes time to scout talent or in hiring firms and consultants.

Over the last year and a half, our team at the Green Market Report has created a running list of the top communication professionals that we feel warrant recognition. After careful consideration among the GMR team, we have selected the top ten that we feel you and your company can engage with effectively. We feel comfortable recommending each person in this group for their work and accomplishments within their special areas of the industry for communications.

Each one of these individuals rank among the most knowledgeable, influential, helpful and professional to work with.
