Lenny Lind is President of CoVision, which has supported organization development projects with appropriate technologies since 1985. In 1991, CoVision began fielding a portable groupware system for meetings--Council--through which anonymous feedback from participants allows the views of a whole group to be addressed while all are still convened. To date, 2500 meetings have been supported by the firm. In 1997, work began on WebCouncil--an online collaboration platform for dispersed teams. This was the system used to host a Delphi conference moderated by Saul Eisen, to consider future OD intervention strategies, and the continuing professional development of OD practitioners.

Lenny is Co-author of "Facilitator's Guide to Participatory Decision-Making", 1996 (2nd ed., Jossey-Bass, 2004).

She also leads workshops in Dynamic Facilitation, a non-linear approach for transforming conflict into creativity.

In addition to completing the Master's program in Organization Development at Sonoma State (2002), Rosa also has professional degrees in multicultural education and in social work. At various times, she has worked as a teacher, translator, writer of educational materials, case manager, and psychotherapist.

Rosa's appreciation for the value of multiple perspectives began early on. Born in Peru to a Spanish-speaking family, she attended a German school for a few years before moving to the United States as a child. After living in California for several decades, she now lives with her husband in the Berkshires in Massachusetts.
