The importance of the digital health revolution in managing and keeping populations healthy cannot be understated. Nor can Athenahealth's role in advancing the state of digital health tech and electronic health records.

As a testament to its on-the-cusp innovations, last month it announced a new care coordination and communication app for the Apple Watch designed to keep health clinicians connected to vital information wherever they are. It's just the latest in a host of Athenahealth solutions that advance the state of patient care.

It's why we're delighted that Rob Cosinuke, CMO at Athenahealth, will be speaking at GrowthBeat Summit in Boston, coming up on June 1 and 2. As the marketing lead in a very disruptive B2B field with a highly specialized target audience, Cosinuke brings a unique perspective to the invitation-only summit of CMOs.

Cosinuke joined Athenahealth in 2008, and most recently, in addition to his role as CMO, has taken on the role of acting president of Epocrates, the number one medical reference app, acquired by Athenahealth in 2013. Doctors and health care providers rely on the app for instant access to drug information, clinical practice guidelines, formularies, and more. Cosinuke is also responsible for the newly formed Athenahealth "Lite" division which includes Epocrates, Athena Coordinator Core, and Athena Marketing.
