Since taking office in 2016, District Attorney Michael McMahon transformed the Richmond County District Attorney’s Office (RCDA) into a modern prosecutor’s office, with a laser-like focus on vigorously prosecuting drivers of crime and those who victimize our neighbors, on utilizing the leverage of the criminal justice system to help those battling addiction and mental health issues, on developing innovative community crime prevention strategies, and on bridge-building between law enforcement and the communities we protect.

Under DA McMahon’s leadership, the office regularly boasts a higher trial conviction rate than the other four boroughs, a shorter arrest-to-arraignment time, a common-sense approach to alternative to incarceration programming offered to those in need, and through this work has maintained Staten Island’s place as the safest borough in New York City and the safest community of its size in the nation.

DA McMahon has utilized his broad and deep experience in law and public service to effectively and efficiently tackle the borough’s public safety issues he promised Staten Islanders he would address. Thanks to his relentless advocacy and the support of the people of Staten Island, the office has doubled the number of Assistant District Attorney’s on staff while greatly expanding the number of support staff as well.

Equipped with these much-needed staff increases, DA McMahon has created several new Bureaus and Units to more effectively fight and prevent crime on Staten Island, including a Domestic Violence Bureau, Economic Crimes Bureau, Animal Cruelty Unit, Immigrant Affairs Unit, CyberCrimes Unit, Elder Abuse Unit, Conviction Integrity Review Unit and more.

Chief among the demanding public safety issues facing Staten Island is the ongoing drug epidemic that continues to take a terrible toll on the borough. From Day One, DA McMahon gathered law enforcement and public health professionals to radically change the way the District Attorney’s office approached the issue. He successfully secured funding to create and expand the office’s Narcotics-Investigations Bureau, which continues to investigate and prosecute hundreds of major drug cases each year. Working together with the NYPD, DA McMahon created the Overdose Response Initiative (ORI) to investigate all drug overdoses on Staten Island in order to trace back the source of the illicit drugs and hold dealers more accountable. ORI has led to dozens of major investigations and takedowns, resulting in successful prosecutions of Staten Island’s most dangerous and notorious drug dealers. Due to its success, ORI has been duplicated across the rest of New York City.

Simultaneously, DA McMahon has dramatically expanded the office’s efforts to help Staten Islanders suffering from addiction illness. In 2017, DA McMahon launched RCDA’s Heroin Overdose Prevention & Education (HOPE) program following months of collaborative work between his office, the public health community, the NYPD, and numerous other community and government agencies. HOPE is a first-of-its kind diversion program in New York City, which redirects low-level drug offenders on Staten Island, pre-arraignment, to community-based health and treatment services, instead of jail and prosecution. In the years since its inception, the HOPE program has helped thousands of Staten Islanders gain access to treatment services. HOPE has since been expanded to offer these life-saving resources to a greater population of individuals with underlying addiction issues.

DA McMahon has also taken a holistic, person-centered approach to the hidden scourge of domestic violence on Staten Island. He created RCDA’s first dedicated Domestic Violence Bureau, expanding it in recent years to meet the many challenges associated with domestic violence cases. Additional staff has been dedicated full-time to these cases, and misdemeanor domestic violence cases are now handled in a vertical prosecution style to better serve victims. McMahon also introduced new procedures to more quickly engage and serve victims, including the institution of vertical prosecution and an e-signature corroboration procedure which have helped cut the office’s dismissal rate in these cases in half.

After the passage of Albany’s so-called criminal justice reforms in 2019, DA McMahon has been an outspoken voice in demanding major revisions to these failed policies, including an overhaul of the state’s bail system to allow judges to detain pre-trial those who pose a threat to public safety, a model followed in every state except New York. DA McMahon has also called for revisions to the state’s discovery laws, which now impose an unreasonable burden on prosecutors forced to meet unrealistic deadlines while making it harder to keep victims and witnesses safe. He has also continually called for a restoration of adequate NYPD manpower on Staten Island, for the strengthening of our state’s drug laws and animal cruelty laws, and for mandatory drug prevention education in our schools. DA McMahon considers this advocacy one of his most important obligations as Staten Island’s chief law enforcement officer, as the safety of his constituents must not fall victim to misguided, idealistic policies from inexperienced, naïve legislators.

Prior to serving as District Attorney, McMahon was extremely active in a career serving the people of Staten Island on the local, city, state, and federal levels. He began as a local civic association and community board member, and then became counsel to two New York State Assembly members and a City Councilman. In 2001, McMahon successfully ran for the North Shore City Council seat himself, where he served for nearly a decade. McMahon professionalized the Council office, implementing ethical and accountability standards. At the same time, he became the first Chair of the Committee on Sanitation and passed a twenty-year plan that put a lock forever on the Fresh Kills Landfill, converted it to parkland, and saved and expanded recycling. He also passed laws to reign in in the Island’s wild overdevelopment, mandated nurses in every school and forced the City to expand ferry service. In November 2008, McMahon was elected to represent Staten Island and Southern Brooklyn in the U.S. House of Representatives. Here, McMahon continued to successfully represent his constituents by helping pass the James Zadroga 9/11 Compensation law, and the legislation that created the Iron Dome air defense system over Israel. He created the Invisible Wounds Caucus which focused on Veterans’ Mental Health issues including the unacceptable rash of suicides. McMahon also secured the funding to expand and modernize the stretch of the Staten Island Expressway between Victory Boulevard and the Verrazano Bridge, the complete renovation of the St. George Ferry Terminal, and the reconstruction of subway stations in Brooklyn.

McMahon was born and raised as one of seven children in the Stapleton neighborhood of Staten Island, and is a graduate of St. Joseph Hill Academy, Monsignor Farrell High School, New York University and New York Law School. McMahon is married to Supreme Court Justice Judith N. McMahon and they have two children, their son Joseph, now married to Irina, and their daughter Julia.
