The president of St. Joseph’s Academy, Sister Adele Lambert, CSJ, has announced she is retiring in May at the end of the 2011-12 academic year.

Linda Harvison is continuing as the Baton Rouge school’s principal. Harvison is the first lay person to hold that post.

Both women assumed their current positions in 2004, when the school shifted from having a lone principal to a president-principal division of power.

Lambert is a 1954 graduate of the all girls Catholic high school.

According to the announcement, before becoming St. Joseph’s president, Lambert served on the faculty and as principal of schools in Baton Rouge and New Orleans, as well as on the faculty of a school in Bay St. Louis, Miss. She returned to her alma mater in 2004 from the Archdiocese of New Orleans, where she held several positions.

A leadership search committee has been formed, chaired by Sister Lucy Silvio, chair of the board of directors for Congregation of St. Joseph Ministries. The committee will launch a nationwide search in October with the goal of hiring the next president by December, according to the announcement.
