Global CEO, McCann Health
By Bill Kolb, global president, diversified agencies, McCann Worldgroup
I have a simple belief: Don’t just be on a client’s business, be in its business. There is no better example of this than John Cahill.
Under John’s leadership, our business has thrived. His passion, creativity, deep knowledge of the field, and devotion to global and public health have all contributed to our team’s success. It comes as no surprise John has earned a spot on this prestigious list for the third year in a row.
Whether leading the world’s most connected community of health and wellness experts across six continents or impacting policies in countries and governments that save lives, John’s ability to influence and impact health has led McCann Health to become a powerful voice for change in healthcare.
His humane approach has helped build McCann Health into a powerful organization with a global footprint committed to helping healthcare brands and businesses play a meaningful role in people’s lives.
