The 9/11 Memorial will host its third annual 5K Run/Walk and Family Day to raise awareness about the National September 11 Memorial & Museum and to encourage volunteerism in honor of 9/11. The IAB is proud to fundraise and participate for this important initiative.
The IAB will sponsor the registration costs of any employee that wishes to participate in the actual run/walk on April 26. Employees can still fundraise for the campaign even if they do not register for the day-of event.
