Dr. Gallivan was a prominent native of Braintree and his career was very well rounded. He was a WWI veteran; he served the staff of the South Shore Hospital in Weymouth as well as Saint Elizabeth’s Hospital in Brighton. He also served as the Assistant Medical Examiner for Norfolk County.
Dr. Gallivan practiced medicine on the first floor of his home while he and his family lived on the second floor. The house remained within the Gallivan family until the 1960s when it was acquired by a dentist for use as a dental practice. In 2005 the house was purchased by the Braintree Historical Society and it is still awaiting interior and exterior renovations.
