Carmel Catholic High School in Mundelein announced Thursday that Judith Mucheck has resigned as president effective Jan. 3.
No reason was given for the action by Mucheck, who has served in that position for 7½ years. No additional information is available, officials said.
"We thank Dr. Mucheck for her service and wish her the best in her future endeavors," Ted Bond Jr., chairman of the high school board of directors, said in a statement.
Mucheck was cited for her oversight of the planning and construction of a new Information Commons and a 33,000-square-foot Fine and Performing Arts Center, which was dedicated last summer. The $6.2 million project was funded through a school capital campaign.
According to the school, which enrolls about 1,350 students each year, Mucheck also helped implement the first one-to-one computing program in Lake County, in which all Carmel students were issued tablet computers.
Details on the search for a new president were not provided, although the school said every effort will be taken to meet the needs of students and families.
"Carmel Catholic is very fortunate to be comprised of a community of professionals who will carry on with the same excellence for which the school is known," according to the statement.
Parents were notified of Mucheck's resignation last weekend in an email from Principal Mark Ostap. The notification did not say why Mucheck left.
She was not available for comment Thursday.
Mucheck, 52, a former nun and career educator, in 2006 replaced Sister Mary Frances McLaughlin, who was Carmel's president for 10 years. Mucheck had served as the superintendent of schools for the Catholic Archdiocese of Atlanta.
Carmel is a Catholic, college preparatory and secondary school for young men and women in grades 9 through 12. It is jointly sponsored by the Sisters of Charity of the Blessed Virgin Mary (BVM) and the Order of Carmelites (O. Carm).
