Parish History
In the 1920's, Rev. John B. Foley, pastor of St. Patrick Church of Wadsworth, Illinois, initiated efforts to organize a parish in Grayslake. A small parcel of land was purchased and plans were made to build a chapel. Before plans could be completed, Father Foley died on October 9th, 1927. 
In June, 1930, in the midst of the Depression, George Cardinal Mundelein appointed Rev. Joseph F. Barrett as pastor of the newly formed parish of St. Gilbert in Grayslake, Illinois. With the encouragement of many Grayslake businessmen, the 40 families of St. Gilbert parish were able to finance the construction of a brick church and rectory of Belvidere Road. Cardinal Mundelein dedicated the new church on July 24, 1932. Two summer residents of St. Gilbert Parish, Captain McCormick and Sergeant John Lee of the Chicago Police Department promoted fund raising events with the help of other parishioners. By 1935, St. Gilbert parish numbered 77 families.
According to reports, men and women from St. Gilbert parish in Grayslake spent three hours every night (after working a full day in factories, on farms, and in offices), constructing a school and convent. The school was being renovated from Dr. Anderson's Clinic to accommodate the children attending grade school. The Sisters of Charity of the Blessed Virgin Mary taught 120 children. A smaller building, complete with child-size furniture, electric trains, dolls, tin soldiers and games, served as a kindergarten. Samuel Cardinal Stritch dedicated St. Gilbert School on November 6, 1949. In 1954, 492 students were enrolled in the parish school.
In 1961, the convent was completed. Four years later, a new church was finished with the first Mass celebrated on Christmas Eve. A Parish Center/Gym was built in 1988 and in 1996, the convent was converted into a Junior High School and offices for Religious Education. Our most recent building project was the renovation of the church which was dedicated June, 2005, our parish's 75th anniversary.
We continue traditions of our patron, St. Gilbert of Sempringham (1083-1189), by sharing what we have with each other and the poor by coming together in prayer and in Eucharist.
