It's a time of transition for the Aberdeen Catholic School System.
The school system's longtime athletic director will retire at the end of the school year.
Tom Murphy, 65, has been athletic director since 1985. He began working in the Aberdeen Catholic School System in fall 1972.
During his career with Roncalli, Murphy, a junior high science teacher, also coached boys' and girls' basketball, junior high football and track for the school.
"It just felt like it was the right time to retire, he said.
He has yet to finalize retirement plans, but he said he is leaning toward moving to Sioux Falls to be close to his children and grandchildren.
He said he's looking forward to spending more time with his family.
There will also be changes to school administration.
Roncalli schools president Jim Hamburge resigned from his position Wednesday at a meeting of the Aberdeen Catholic School System School Board.
In a letter he wrote for Roncalli parents, Hamburge explained that his leadership style and his perspectives on the future of the school differed from the board's.
"Thus, I have chosen to resign from my position as president of the Aberdeen Catholic School System effective immediately," he wrote.
Hamburge thanked parents for their support of the school and his leadership in the letter.
A temporary administrative plan is in the works. Hamburge officially began his tenure at Roncalli in July 2011.
I have been honored and blessed to have been entrusted with the education of your children, said the letter intended for parents. I absolutely love Roncalli, and I will always cherish my time here with you and your children. I wish you and Roncalli nothing but the best in the years to come.
Hamburge, a native of St. Paul, Minn., said he will be returning to the Twin Cities area.
He plans to retire or continue his involvement in Catholic education part-time.
