mom2boys,
DeMolay is a character and leadership building organization for young men ages 12-20 years old. It does have some ties to the Masonic fraternity in that they are generally the sponsors of the chapters, but they do not have to be. DeMolay chapters often meet in the Masonic centers because they are usually given the space rent free.
In comparison with the Boy Scouts, DeMolay often teases that Boy Scouts do outdoors, and we do indoors. While you may learn knots, and fire building in scouts, you will learn public speaking, parlimentary procedure, time management, etc with DeMolay.
Sometimes people who don't know any better claim DeMolay is a secret organization, but thats not true at all. They do however have "secrets" like handshakes, and passwords, but what kind of boy's club would they be without those? :^) There are no secrets from parents and all activities are supervised by criminally background checked trained adults.
