District 18Biography:

Since being elected to the Nassau County Legislature as Legislator for the 18th Legislative District, Don has made it a priority to fight for taxpayers. As a homeowner with a young family taxes are not a theoretical issue for him, he pays them also. During his time as a county legislator he has never voted for a tax increase. County government has become smaller and the county has become safer during that time. He will continue to work to make our communities safe to raise families while keeping county government smaller, transparent and accountable.
