Matthew Green (February 10, 1987 - May 12, 2021)
It is with a heavy heart that the League informs our community of the passing of Matthew Green. If you have ever sent in a donation to the League, ever renewed your membership by mail, ever bought a pair of socks or a water bottle from us -- if you’ve ordered a box of Quick Guides or registered for an LCI Seminar or attended a National Bike Summit, Matthew Green touched your life.
Matt was an integral part of the League. He was a beloved son, an adored younger brother, and a light in the lives of all who knew him. On May 12, Matt’s light tragically passed from this world. Each of us feels his loss, and none feels it more starkly than his family. We are fortunate to have been able to know Matt, to share his joy in all things gaming and geeky, and to be uplifted by his big, bright smile and his gentle demeanor. The League staff will not be the same without him.
