He practiced at a private
law firm prior to entering local politics. In 1953, Kinsella was elected to the Hartford City Council when he was 29 years old. The city council also elected him Deputy Mayor, a position he held until he became Mayor of Hartford in 1957. Kinsella was elected mayor and sworn into office in 1957. He was re-elected to a second term in 1959 and served until late 1960. Kinsella left the mayor's office in 1960 when he was elected a Hartford
probate judge (Judge of Probate for the District of Hartford). He remained a probate judge in 1984. That same year, Kinsella retired from the bench as he was facing possible
impeachment over the handling of the estate of
Ethel Frances Donaghue, a wealthy former lawyer from neighboring
West Hartford, Connecticut. He was never impeached. Kinsella, who remained a working
attorney until late in life, continued to pursue philanthropic endeavors for Hartford after leaving the court. He supported
beautification efforts, including the construction of a city park and jogging track at Broad Street and Farmington Avenue in Hartford. He purchased
police horses for the Hartford Police Department and lighting for
Hartford City Hall. Kinsella also created
scholarships, acquired a piano for the Hartford library, and installed a notable rose window at the Charter Oak Cultural Center. == Personal life ==
