Nine months earlier, veteran behavioral health exec Joey Jacobs takes the reins at Atlanta-based Acadia and moves the offices to Nashville to begin a massive expansion effort. He is joined by most of the former management team of his predecessor company, Psychiatric Solutions Inc.

Acadia begins to trade on the NASDAQ after completing a merger with Pioneer Behavioral Health, a public company on the American Stock Exchange. With funds raised by the IPO, as well as investments from capital partners, the company rapidly acquires behavioral health providers across the country.

In 2014, Acadia pays $1.18 billion to purchase CRC Health Group Inc., the nation’s largest behavioral health provider at the time.
