He is a patient advocate and professional who has been a pioneer in online mental health. While he has been involved in online services as early as 1981, he began on the Internet in 1991 by disseminating information on numerous mental health topics. Dr. Grohol quickly realized that it was difficult to find pertinent and relevant mental health information online, and so began compiling indices of newsgroup, mailing list, and World Wide Web resources. Contributing to Usenet newsgroups, he soon became the moderator of two newsgroups he founded, sci.psychology.research and sci.psychology.announce. Dr. Grohol has also founded over two dozen additional newsgroups devoted to psychology and self-help support topics on-line.
