BRAINTREE -- The Archdiocese of Boston announced July 19 that after five years of service superintendent of Catholic Schools Mary Grassa O'Neill will step down as of Aug. 15.

Vicar general Bishop Robert P. Deeley announced the development via an email to employees of the archdiocese, with comments from Cardinal Seán P. O'Malley.

"We are indebted to Dr. O'Neill for her many efforts to help the students we serve fully achieve their potential. Our schools have realized significant improvements in academics while continuing to strengthen their Catholic identity and faith formation. The Catholic schools in the Archdiocese of Boston are in a much better place today because of Dr. O'Neill's dedication and commitment," Cardinal O'Malley said.

The vicar general said O'Neill's work to reform and strengthen Catholic education in the archdiocese has established a strong foundation for the years ahead. The email listed her achievements as the reorganization of the Catholic Schools Office and making a priority of support for pastors, principals, faculty and staff at archdiocese schools.

"Her contributions have brought great benefit to the more than 41,000 students who are enrolled in Catholic schools in the archdiocese. She has put us on the path of revitalizing and reinvigorating Catholic education throughout the archdiocese by developing and implementing the Cardinal's Strategic Plan for Catholic Education," Bishop Deeley said in the email.

The archdiocese said a process will be implemented for the selection of a new secretary for education or superintendent and further announcements will be made regarding an interim appointment for the position.

"It was an honor to work with the Catholic Schools Council and Catholic School Office team to serve our wonderful students and families. Among the many blessings of this assignment are our dedicated and talented pastors, principals, heads of school, teachers and benefactors. All ensure that our students get the benefit of a first class Catholic education," O'Neill said.
