The Stuttering Foundation provides free online resources, services and support to those who stutter and their families, as well as support for research into the causes of stuttering. We are a tax-exempt organization under section 501(c)(3) of the Internal Revenue Code and are classified as a private operating foundation as defined in section 4942(j)(3). As the first and the largest nonprofit charitable organization in the world working toward the prevention and improved treatment of stuttering, we reach more than a million people annually. We also offer extensive training programs on stuttering for professionals. We hope that we may be of service to you.
