About Us

The Mood Disorder Support Group of Long Island was founded on the idea of helping those in need. Ever since our organization was established, we have endeavored to provide help where the need is greatest.


Our team is made up entirely of volunteers. We advocate for those who need our help. Even a little help goes a long way.


That is why we are especially happy to find new volunteers who share our commitment to doing good in the world. Do you want to support us by helping with our work? Then do not hesitate to contact us. A helping hand is always greatly appreciated!
