John J. Mueller comes to the MTA following 28 years of service at the Yonkers Police Department. Mueller oversees the more than 1,000-member MTA Police Department that is responsible for patrolling and securing the MTA’s operating region, which stretches from Montauk to Poughkeepsie.  

Mueller began his law enforcement career in 1992 with the NYPD, joining Yonkers PD in 1994 as an officer in the 4th Precinct. Mueller rose the ranks over the years, leading up to his 2019 appointment as Police Commissioner. Among his many credentials during his recent 10 years at Yonkers PD, the City of Yonkers saw a 45% reduction in crime through a hyper focused, precision policing philosophy. This reduction has been credited to focused community engagement by officers, a program Mueller pushed during his time as the Commanding Officer of the 4th Precinct.  

Born and raised in Yonkers, Mueller holds a graduate degree from John Jay College of Criminal Justice in New York City. He has attended the Police Executive Research Forum, the United States Naval Postgraduate School's Center for Defense and Homeland Security, and is a graduate of the FBI National Academy. He has been married to his wife Donna for 28 years. The couple has three sons: Jack, Sean, and Shane.
