About Elva


Elva has over 20 years of international experience in the research and application of Hall-Tonna values technology in organizational and strategic business development for corporate organizations, non-profits, and academic institutions.

She is passionate about bringing values technology to both individuals and groups because it allows all of us to explore, discover and crystallize the underlying motivations that can either block our abilities to realize goals or propel us towards success. She delights in the synergistic partnership with her clients that allows them to accomplish their objectives.

Elva also maintains a Hall-Tonna values-based integral coaching practice that specializes in the professional and personal development of leaders at all levels.

Elva has an M.A in Counseling Psychology from Santa Clara University of California.  She teaches at Saint Mary’s College of California in the Masters in Leadership Program.  She has been a regular guest lecturer in Spain (Universidad de Deusto), Mexico (TEC de Monterrey), and at Santa Clara University.
