White House

The National Association of Manufacturers (NAM) is the largest manufacturing association in the United States, representing small and large manufacturers in every industrial sector and in all 50 states. Manufacturing employs more than 12 million men and women, contributes $2.25 trillion to the U.S. economy annually, has the largest economic impact of any major sector and accounts for more than three-quarters of private-sector research and development. The NAM is the powerful voice of the manufacturing community and the leading advocate for a policy agenda that helps manufacturers compete in the global economy and create jobs across the United States. 

Jamison Door Company had the opportunity to share in NAM's tax reform event in the Rose Garden of the White House where President Donald Trump highlighted the historic results of the NAM's outlook survey and the manufacturing industry's positive economic outlook.

As spoken by NAM President and CEO Jay Timmons, "Manufacturers are proving that when the President and lawmakers deliver on policy, we will deliver for the American people."
