Green Tree American Legion Post 823 meets on the third Wednesday of each month at 8:00 P.M. at the Green Tree Fire Hall. Veterans that served during the following dates of conflicts are eligible to join The American Legion: December 7, 1941 to December 31, 1946, June 25, 1950 to January 31, 1955, February 28, 1961 to May 7, 1975, August 24, 1982 to July 31, 1984, December 20, 1989 to January 31, 1990, and August 2, 1990 to the present.

     Green Tree Post 823 participates in all of Green Tree Borough's events and have quite a few of their own events. The members of the Post do the flag raising at the annual 4th of July celebration and also the two days of Octoberfest, as well as having a booth at Octoberfest. Post 823 also sponsors the annual Halloween parade for the children of the Borough along with the Green Tree Recreation Committee. On Memorial Day a ceremony is held at the monument followed by a service at St Margaret of Scotland and on Flag Day a ceremony is held at the monument. Also during May the post places flags on the graves of veterans at three cemeteries. The Post also presents an American Legion school award to two students at St. Margaret of Scotland elementary school.

     Post 823 has a poppy drive the first weekend of May, the proceeds of which goes to entertaining hospitalized veterans. We go to the John Heinz V.A. Hospital in Aspinwall and hold a bingo and bring refreshments for the patients. The prizes for bingo are canteen books that the veterans can use to buy whatever they need. The past several years we have had two busloads of patients come to the fire hall for a lunch and bingo, a much needed break for these men and women. Post 823's efforts to help hospitalized veterans were recognized by the Department of Pennsylvania at the state convention this year. The Post was the recipient of an award for their work, which we are very proud of due to the fact that there are 747 Posts in PA and many are much larger than us.
