Resurrection's second pastor cane to Brookline on March 3, 1955, from Our Lady of Grace parish, Scott Township. Father Oliver D. Keefer wasted no time making preparations for the parish's still-growing population. He immediately launched a very extensive improvement campaign in the summer of 1955 which included repairs and renovations to the school and church. The cost was approximately $70,000.

One year later, Father Keefer announced plans for the construction of a school annex and a new convent at a cost of about $500,000. During the 1956-'57 school year, when construction began, the sisters moved to the rectory, in some cases sleeping three to a room. At the same time the priests moved to 1111 Creedmoor Ave., the part of the convent built in 1926. Plans called for the demolition of the old King house at 1115 (which once served as a rectory and then a convent). Also demolished was the building at 1113 Creedmoor, the oldest part of the convent.

The annex, located next to the old school building, was completed in time for the beginning of the September '57 school year. It provided six additional classrooms which were occupied by the 7th and 8th grades. Unfortunately, the convent wasn't ready until late in November. So, with the priests already moved back into the rectory, the sisters had to commute from various locations around southern and western sections of the city.

The new convent and annex were dedicated on November 24, 1957, in a ceremony led by Auxiliary Bishop Coleman Carroll who had been an assistant at Resurrection from 1930 to 1934.
