Our Team

JD is a Senior Director at Oratium. He works primarily with companies and business executives to improve their communication skills across a wide range of industries and business functions – including Sales, Strategy, Market Insights and Internal Communications, as well as TED speaker coaching. To span such a diverse terrain, JD focuses on becoming a student of the client’s business and their key outcomes in order to best advise them on how to apply Oratium’s doctrine to achieve their desired results.

With over 20 years of experience advising Fortune 500 companies globally–including a three-year stint in Sydney, Australia working with Asia Pacific organizations–JD brings the balance of business savvy and youthful passion to all of his client engagements.

The most critical of those engagements are with his wife, Jennifer, who is a communications consultant and a total Oratium convert. From Washington, D.C. to Sydney and back to D.C. again, they now live in Saint Michaels, Maryland-on the Chesapeake Bay’s Eastern Shore. They’ve enjoyed a life well-travelled. Adventure, both personal and professional, is often just a plane (or car) ride away. Just the way they like it.

Michael Hubble is Managing Director at Oratium. He has spent the past 20 years creating and presenting best-practice research for senior executives of health systems and corporations.

Most recently, Michael was a Managing Director and national spokesperson for The Advisory Board, a health care consultancy serving 2,400 of America’s hospitals and health systems. His areas of focus were health system strategy, health system economics, and health policy.

Before joining the Advisory Board, Michael spent 11 years with the Corporate Executive Board, a leading management consultancy. At CEB, he worked with over 500 clients, including more than half of the Fortune 100, advising executive teams and boards of directors on organizational strategy, change management, and marketing strategy.
