When I attended a course in Detroit in 2008, we meet with representatives from various groups that are trying to change the life of individuals and communities for the better. An example of that:
COTS exists to alleviate homelessness by providing an array of services that enable people to achieve self-sufficiency and obtain quality affordable housing. COTS also exists to advocate for long-term solutions to the problems of homelessness.
