Few are as memorable as Dan Kelleher: an absolute natural who quite simply, flat out, just gets "it" and just gets it done. By that I mean, the meetings he books, the business he generates, and the people who can't wait to work with him are truly impressive. He knows digital and mobile inside and out -- understanding not just his platforms, but what his clients and agencies want, because he invests in and consults with each -- and advocates for those needs, without fail. Which leads to better campaigns, better results, and happy customers who can't wait to work with him again. And again. And again. Which, as a marketer, is all you can ask for in your sales leadership."
