Four Sisters Inns, a collection of 18 boutique inns and hotels located in California, has been acquired by an in-house executive team led by long-time company employees Tamara Mims and Joni Costa. Mims, formerly VP of Four Sisters Inns, has been named president of the hotel management company. Costa retains her position as chief financial officer.

Shelley Post, one of the original “four sisters” for whom the group is named, is transitioning from president to a new role: founder and senior consultant. Going forward, Post will continue to work on company strategy and ensuring a smooth transition.

Under Post’s stewardship, Four Sisters Inns has grown from its 1970s roots as a Pacific Grove bed-and-breakfast inn to a boutique hotel group with 18 properties throughout California, more than 300 employees and a loyal following of guests. Post ran her first inn during the summer when she was 16 years old.

“The time has come for me to pass the reins to a new generation, and I’m thrilled to be handing them to two trusted senior employees who have been part of our team for so long,” Post said in a statement.

Mims received her bachelor’s degree in sociology from the University of California, Berkeley. She joined Four Sisters Inns in 2002 as director of marketing and was named VP in 2012. In addition to overseeing marketing efforts, Mims has been involved in operations, hotel transitions, consulting, technology solutions and staff training. Since 2013, she and Costa have taken leadership roles as several inns joined the Four Sisters Inns collection, among them the Milliken Creek Inn and Spa in Napa, Coachman’s Inn in Carmel-by-the-Sea and the Kenwood Inn and Spa in Sonoma Valley.

“We’ve been actively working on a succession plan to ensure continuity for our guests, employees and investors,” Mims said in a statement. “Our team is committed to keeping what has worked so well all these years, in addition to looking at ways to innovate and improve upon the guest experience.”

Costa joined Four Sisters Inn in 1987 as bookkeeper and executive secretary. She was soon promoted to office manager, and in 1995 was named VP of accounting and human resources. In 2014, Costa was named controller, and in 2016, CFO.

“Shelley has created a legacy that I am proud to have helped craft over the last 30 years,” Costa said in a statement. “I am excited for the company’s next chapter.”
