About the Clerk-

Chelsea Peterson, City Clerk/Treasurer

I have worked for the City of Thompson Falls since February of 2007 and really enjoy it! I feel very lucky to work here with a wonderful Staff, City Council Members, Mayor, City Attorney, Judge and Community!

I am a member of the Montana Municipal Clerks Treasures & Finance Officer's Association.

I attended Montana Municipal Institute for Clerks, Treasurers, & Finance Officers conference usually the first week in May every year.

The Montana Municipal Clerks Treasurers & Finance Officer's Association is the State organization that serves as a catalyst for all clerks, treasurers and finance officers in Montana.
