By Thinking in terms of an "adoption triad" may help illuminate the wide reach of adoption, a reach that extends to three primary constituents: adoptees, adoptive parents and birth parents. The Palo Alto Medical Foundation (PAMF) will host a talk Sept. 11 featuring a representative from each major element of the adoptive experience.

The discussion, organized by the Post-Adoption Center for Education and Research (PACER), will emphasize the lifelong impact of adoption and address steps that can be taken to ensure that the impact is enriching.

The event will be presented Sept. 11, 7-8:30 p.m., in the Hearst Center for Health Education, Level 3, PAMF, 795 El Camino Real, Palo Alto. To register, call 853-4873.
