    ADDA is an international, entirely volunteer-run, virtual organization with no physical offices or staff. We do not have a receptionist. However, we do have a dedicated group of volunteers committed to serving the adult ADHD community. For the quickest response, we encourage you to contact us using the email form above. However, if you choose to contact us by telephone, be aware that there will be a delay of several hours to several days before a volunteer can get back to you. We are happy to hear from you, and eager to serve. We will do our best to answer your questions and address your concerns, and we are always working to improve our service. The choice, phone or email, is yours, but please be aware of the limitations of the service we are able to provide.
