Here's a little about those three leaders, who met the challenge of service, response and relief and crisis counseling across the county and globe:

Jay S. Winuk is co-founder and vice president of MyGoodDeed, the nonprofit organization that led the advocacy campaign to establish 9/11 as an annually recognized National Day of Service and Remembrance, which was signed into law by President Obama in April 2009.  On Sept. 11, 2001, Jay lost his younger brother Glenn J. Winuk, an attorney and volunteer firefighter, who was killed in the line of duty when the South Tower collapsed.  Millions of people from all 50 states and countries all over the world now mark Sept. 11 to serve people and communities in need. Also attending will be Bill Keegan of H.E.A.R.T. 911 and a member of the New York Says Thank You Foundation.
