MDI began as a nonprofit, educational organization in 1982 to serve children and adults with dyslexia throughout Michigan. Over the years MDI has emerged as a unique resource and significant educational force in the state. It has attracted national attention and has served as a model for other states. To meet the demand for services, information and consultation from groups and individuals in other states, the Dyslexia Association of America (DAA) was developed in 1994.

From the beginning, MDI/DAA has been under the continuing leadership of Executive Director, Kay M. Howell, M.A.,F/AOGPE. The training and language evaluation programs were developed by John C. Howell, Ph.D.,F/AOGPE. Throughout, success has depended on the effort and dedication of the directors, the highly trained and committed staff and instructors, the caring volunteers, the generous contributions from individuals and corporations, and grants from foundations. Thousands in Michigan and in the nation have received information, training, and educational services in their local communities because so many people care and have become involved. While proud of its history and accomplishments, MDI/DAA will not rest until the "new world for those with dyslexia" exists.

MDI believes that teamwork with other groups, community partnerships, development of volunteers and the assertive leadership of those with dyslexia will bring about this new world.
