I am extraordinarily proud to live in St. Mary’s County and feel blessed to have met so many great people who live, work, and own businesses here. It’s the reason I am so determined to combat the county’s rapidly increasing violent crime and exceedingly high number of traffic-related fatalities.

John O'Connor is in his second term representing Commissioner District 3 (Charlotte Hall, Mechanicsville, Golden Beach and the Seventh District). He was raised on Long Island, New York, where he was raised in a culture of public service as his family has served the NYPD for several generations.
