Welcome to the information portal for the Missouri Legislative House District No. 99. The Convention of States Missouri team is available to help you with any questions you may have about our efforts to call an Article V convention to propose amendments to the U.S. Constitution to rein in our federal government and return power back to the states and the people.
The Missouri Information Page and the COS Missouri Lookup Tools for Getting Involved in Your Government Page contain links and tools to help you become a better self-governing citizen. Following is information specific to your Missouri House District. This is an open-access webpage and you are welcome to share it with family, friends and neighbors.
Please note that a House District can be nested within a Senate District or it can overlap two or more Senate Districts. If more than one Senate District is shown, please refer to the lookup-tools page shown above to find your senator.
