John Tooker has announced that he will step down from his position as the executive vice president and CEO of the 129,000-member American College of Physicians, the nation's second-largest physician organization.
He will stay on the job until a replacement is named which is expected to happen in the next six to 12 months, according to a news release.
Tooker, 65, joined the Philadelphia-based internal medicine specialty organization in 1995, serving as deputy executive vice president and chief operating officer. He was promoted to the post of executive vice president and CEO on July 1, 2002. Under his leadership, the ACP's membership has increased 12%.
Earlier this year, Tooker was voted No. 86 on the 100 Most Powerful People in Healthcare ranking by the readers of Modern Healthcare and Modern Physician. Tooker attributed his selection to the growing recognition of the importance of primary care, and the role his organization has played in healthcare access, delivery, workforce and payment reform.
