The Myositis Association

The Myositis Association (TMA) is a non-profit, voluntary health agency dedicated to improving the lives of people affected by myositis. Founded in 1993, TMA has grown from 16 patients, who helped form the organization, to more than 6,000 members who have been served by TMA. TMA is governed by a volunteer Board of Directors that includes patients, family members and interested professionals, bringing diverse strengths and perspectives to the organization. Through member newsletters, publications, support groups, research and advocacy, TMA helps those who have myositis today and works to prevent any others from having to experience myositis in the future.
