History of Mercy in Jefferson County

History & Heritage

1953

During the summer, local residents establish the first board of directors for Jefferson Memorial Hospital and elect Amos A. Govero as chairman. With help from a $375,000 federal grant, Govero and the board begin raising nearly $1 million to build a hospital for their community.

1957

After several years of community fundraising, that vision becomes reality. Jefferson Memorial Hospital opens May 15 with three doctors, 13 employees and 50 patient beds.

Less than a decade after opening, another successful fundraising campaign allows the hospital to double in size. A second floor is added, expanding patient capacity to 98 beds.
