About Us



Several years ago, the current directors of our organization decided to create The Mood Disorder Support Group of Long Island to give everyone who is interested, the opportunity to help those in need. Helping the community grew to become a permanent part of the lives of our members.

We are now in 3 Counties

We span three counties and five hospitals!
