United Building Maintenance Corporation is the leading provider of janitorial services in New York City


Oliver Madison's Philosophy:

  • All things can be achieved with hard work.
  • The armed forces gave him the discipline to be successful.
  • Education is the key to a young persons success, regardless of current circumstance.
  • Food is a basic need.  If you are hungry, eating is your only goal.
  • Remember where you come from and give back.

At United, it is our goal to ensure that our giving speaks to these values.
