A news release from the college (PDF) said the group had experienced “unprecedented” membership growth during his tenure, resulting in more than 40,000 members in the U.S. and 73 countries.
The group also added 81 local chapters throughout the U.S., Canada and Mexico under his watch, the release said.
Dolan said working as ACHE's top leader has been one of the greatest privileges of his life. "I am looking forward, in the future, to spending more time with my family and friends, serving as en executive coach and consultant, and pursuing long neglected hobbies," he said in the release.
The ACHE and a related foundation counted more than $25 million in revenue in 2010 and paid Dolan a salary of $833,000, according to tax filings. Revenue from membership dues showed a small decline between 2009 and 2010 to $6.8 million from $6.9 million the year before.
In addition to working for the ACHE, Dolan has been active with the American Society of Association Executives and the Board of Overseers for the Malcolm Baldrige National Quality Award.
Dolan has appeared on every annual Modern Healthcare list of the 100 most influential figures in healthcare since the survey began in 2002, including this past year's ranking where he was No. 72.
