Westbrook High School will have a new principal when classes begin in September.

The Westbrook School Committee voted unanimously Tuesday evening to appoint Kelli A. Deveaux to the position, according to acting Superintendent Marc Gousse.

“We are blessed to have her,” Gousse said. “She is just an exemplary candidate.”

Deveaux has served as assistant principal of Windham High School since 2002. During her time in Windham, Deveaux also served as acting principal in 2008-09.

In her new position, Deveaux will be paid an annual salary of about $104,000. Gousse said she was given a two-year contact.

She will replace former Principal Jon Ross, who started July 1 as the superintendent and principal in Acton, a district with one school that serves grades pre-K through 8. Ross had served as principal of Westbrook High School since 2012.

Gousse is also leaving the Westbrook school district, having accepted as position as superintendent of the Mount Desert Island Regional School System.

He will continue to serve Westbrook on a part-time basis through the end of July as the district continues to search for a new superintendent.

Gousse said Deveaux is taking over leadership of a “good-sized, diverse” high school whose latest enrollment was about 750 students.

Deveaux, who lives in Gorham, was recognized as Maine’s Assistant Principal of the Year in 2014 by the Maine Principals’ Association.

The MPA in 2014 said that Deveaux received the honor based on her accomplishments as a collaborative educational leader, as a role model in the development of a positive school culture, student-centered policies and programs, and as a tireless advocate for assistant principals.

“Ms. Deveaux is a visionary educator who consistently inspires her colleagues to bring their best game to the table when it comes to doing what is right for students,” MPA Executive Director Richard Durost said in a statement issued at the time.

Before becoming the assistant principal at Windham High School, Deveaux worked in the South Portland school system as an English teacher and grant coordinator.

She attended the University of Southern Maine and earned a bachelor’s degree and master’s degree in education from the University of New Hampshire.
