Under Robert’s leadership as CEO, The Advisory Board Company has more than quadrupled in size and now serves nearly 300,000 leaders in over 5,500 hospitals, health systems, and universities worldwide. He has continued to guide the firm’s strategy, keeping our comprehensive research portfolio at the core while expanding our technology, consulting, and data-enabled services capabilities to help members hardwire best practices into their institutions. In health care, our focus is on three critical areas, ensuring that health systems: attract, retain, and engage patients by offering the care they need; deliver the highest standard of care by instituting and consistently following the best protocols; and receive payment for the services they render, so they have the financial stability to serve their communities for the long term. In Education, we deliver significant value by leveraging our data assets and deep expertise to bolster results across the student life cycle, including recruitment, enrollment, retention, and student success.

Robert has also placed immense emphasis on strengthening our communities; the firm has one of the highest rates of employee volunteerism in the nation, with hundreds of millions of dollars’ worth of service work and donations provided to non-profit organizations across his tenure.

Robert was named a “Tech Titan” by Washingtonian Magazine three times, honored as one of the "Power 100" in the Washington Business Journal, won the Ernst & Young LLP Entrepreneur of the Year Award for Business Services in Greater Washington, and has been profiled in the New York Times.
