Dr. Kahane will report directly to athenahealth CEO and Chairman, Jonathan Bush.

Dr. Kahane brings more than 30 years of experience on the front lines of care, as well as driving growth and profitability for a number of healthcare IT businesses. Most recently, Dr. Kahane led significant revenue growth and effected a successful sale as CEO of AMICAS, an image and information management solutions company. Dr. Kahane served as chief strategy officer and vice chairman of the board of VitalWorks, a company that became a leading provider of practice management and EHR software.

Management has a strong game plan and a team with dedicated focus that will put wind at our backs as organizations in this segment of the market looks to wring maximum value out of their IT investments.”

“We’ve made several moves to bolster our ability to identify, sell into, and service existing and prospective enterprise clients,” said Jonathan Bush. “Our resources are now concentrated so we can compete aggressively in this area of the physician market and we look confidently to Stephen to inspire a trusted team of world class advisers.
