A study of 35 nonprofessional helpers, identified as community "guides," focused on the contribution each made to helping marginalized individuals and families become a part of their communities. The lessons learned through these lay helpers can inform a postmodern social work practice that promotes the use of indigenous practice principles appropriate for work with and in culturally distinct communities. The practice wisdom of these guides demonstrates a need for professionals to reposition themselves in the associational life of a community, and to make their practice less visible. It is shown that an effective community-building practice that respects community solutions to individual and community problems requires permeable boundaries on the part of intervening professionals.
