Del McNamara graduated from the University of Virginia with a BS of Accounting and a BS of Finance. He is a Certified Public Accountant — the only one in the General Assembly. He did his Masters Coursework in Taxation at Virginia Tech.
Elected to the Roanoke County Board of Supervisors in 1996, he successfully reduced the Roanoke County budget and never raised a tax.
He was elected to the Virginia House of Delegates in 2018. In his first session, he compiled a solid voting record while fighting for conservative principles of fiscal integrity, protection of constitutional rights, and family values. He currently serves on the House Finance and Counties, Cities, & Towns committees. After noticing his superb expertise of tax policy, House Republican Leadership appointed Del McNamara as whip for the Republicans on the Finance Committee.
