Tommy Siam is the Ward 9 representative on the Florissant City Council, a position he has held since 2015. Tommy moved to St. Louis in 2001 to work for Boeing, where he works on Air Force trainer jets. He moved to North County, where he immediately appreciated its convenience and diversity. When it was time to buy his first house, he chose Florissant. He felt very welcomed by the community. He is an active member of John Knox Presbyterian Church. He lives in the Paddock Hills subdivision, near New Halls Ferry and Parker Roads.

As a councilman, he makes his first priority to respond to residents' concerns. He also works toward code enforcement, economic development, sustainable parks, and public safety issues such as street lighting and speed limits for residential neighborhoods. Tommy believes in government that is responsive to all citizens, and is honored and humbled to serve his home community.
