Almost 3,000 people were killed, and more than 400 of them were emergency responders.
"I can't think of anybody that I've ever spoken to, in the fire service, or civilian, who wasn't impacted by that day," said Pullman Fire Chief Scott LaVielle.
Even though it happened over a decade ago, the Pullman Fire Department held a ceremony Tuesday morning to remember the lives that were lost. And, they will continue to do so for many years to come.
"It helps us, you know, to reflect not only on what happened, but also honor those who made that sacrifice," said LaVielle.
To Fire Chief LaVielle, it's not only important to remember the lives lost in the terrorist attacks on this date, but every day of the year.
"I keep a coin with me that was given to me by my son for the ten year anniversary of 9/11," said LaVielle. "And I keep this with me every day of my life to honor them and to remember the courage and the sacrifice that they made."
