Geoghan was assigned to St. Bernard's Parish in Concord starting on September 22, 1966. He was transferred after seven months there; church records offered no explanation for his reassignment. On April 20, 1967, Geoghan was assigned to St. Paul's Parish in Hingham. Around 1968, a man complained to church authorities that he had caught Geoghan molesting his son. As a result, Geoghan was sent to the Seton Institute in Baltimore, Maryland, for treatment for his pedophilia. In the early 1970s, parishioner Joanne Mueller accused Geoghan of molesting her four young sons. Mueller has said that she informed Paul E. Miceli and he asked her to keep quiet. Miceli disputes her account. The church later reached a settlement with Mueller.
