- Beginning in 1949 on July 7, Father Albert Jasinski was appointed pastor of a new parish named Our Lady of Grace. This new parish had its first Mass celebrated on December 25, 1949 in the Town Theater on Kennedy Avenue.
- Mass continued there until October 29, 1950 when the first Mass was celebrated in the newly renovated former Calvary Baptist Church on Jewett Street. At this time, 272 people gathered to celebrate the Mass.
- With continued growth in the parishioner base, a new addition to the church was dedicated on October 28, 1951. Due to the continued growth of the parish now totaling 540 families, ground was broken on February 6, 1954 for a one story church and 10 classroom school on Highway and Fifth.
- Construction began on July 11, 1954 and was completed on December 1, 1954 when doors were opened for 291 students in grades 1 through 6. The basement church and remaining classrooms were completed in early 1955 and Mass was celebrated in the basement church on April 22, 1955.
- A second story was added to the building to house a library and convent due to increasing school enrollment now at over 700 students and parishioner enrollment totaling 728 families.
- In 1960 marking the tenth anniversary of the parish which now numbered 5,000 members and 1,000 students, Father Jasinski and two assistants and religious from the Sisters of Saint Francis from Mishawaka, now were pressing for expansion. Masses were now being said both in the basement church and cafeteria area.
