Memorial societies are nonsectarian, nonprofit, educational organizations.
There are now more than 150 nonprofit memorial societies in most states of the U.S. and in the provinces of Canada.

In addition, your society supports the social action needed to expand and protect a consumer's last rights. It always pays to plan ahead.
