Jack Polson, CFO and executive vice president of Acadia Healthcare, is vacating those positions at the end of this month to pursue personal interests, company officials announced late Monday.

Polson joined the former Psychiatric Solutions in 1997 and was a core part of the team that built that company before it was acquired by Universal Health Services. His job will be taken over by David Duckworth, the Franklin-based behavioral health venture's chief accounting officer. Duckworth joined Acadia in April of last year after a stint as director of finance for Emdeon.

“We are saddened to announce that Jack Polson is departing Acadia, although we understand his decision to refocus his energy on personal pursuits. We wish him well for the future,” said Joey Jacobs, Acadia’s chairman and CEO.
