Welcome to the website of the Midwestern Society of Orthodontists!

The Midwestern Society of Orthodontists (MSO) is a constituent of the American Association of Orthodontists (AAO). We are comprised of approximately 1,380 members across the component states of Illinois, Iowa, Minnesota, Missouri, Nebraska, North Dakota, South Dakota and Wisconsin, as well as the Canadian province of Manitoba. Since 1939, the MSO has continuously strived to support the AAO mission by providing helpful resources, clear communication and strong leadership to component societies and individual members.
