Troop 483 had its first meeting on January 5, 1954.
Troop 481 had grown too large, so Troop 483 was formed. The troop was sponsored by the Methodist Men’s Club, First Methodist Church of Glendora. Ray Biotto was the Committee Chairman, Larry Ratkoviak was the Scoutmaster and Gordon Stith Jr. was the Senior Patrol Leader. At the first meeting there were 13 scouts.
Originally the troop met at the Scout Hut in the Recreation Park (now known as Finkbiner Park). Some time after 1955 meetings were moved to the United Methodist Church of Glendora where the troop still holds its meetings, most Monday nights at 7:00pm. At the time the troop was formed, Troop 483 was in the Monte Vista District of the San Gabriel Valley Council. Since then Troop 483 has been in the Big Dalton District, the Mountain View District, Valle Del Sol District, and is now in the San Gabriel Valley District in the Greater Los Angeles Council.
