Leadership &
Executive Council

ACHA Officers and Executive Council Members

The American Catholic Historical Association is led by an elected president, an elected nine-person Executive Council, and an executive secretary/treasurer, who is appointed by the Executive Council. Elections, in which all ACHA members are eligible to participate, are held each fall.
Our leadership reflects the wide scope of experience and interests of our membership. Executive Committee representatives are professors at large and small universities, independent scholars, archivists, and graduate students.
