  • The Supervisor and four Council members propose legislation and make policy decisions that directly affect residents.
  • The Supervisor responds to the needs of the community and represents the Town in its dealings with County, State, and Federal Agencies.
  • The Supervisor represents the Town on the Westchester Joint Water Works (WJWW) Board.
  • The Supervisor is a Commissioner of the Larchmont-Mamaroneck Joint Garbage Commission.
