Margaret Sadler spent her career as a Human Resource (HR) executive for multinational corporations working all over the globe helping managers resolve organization problems. Throughout her career she took time to be involved with many nonprofit and government agencies from chairing a Civil Service Commission to a seat on an Historic House Board. She currently serves as Board Chair of the Pennsylvania Horticultural Society (PHS).

Since 2012 Margaret Sadler has been doing pro bono consulting with nonprofits that otherwise could not afford a consultant. Clients have included social service and social change, cultural and educational organizations—some only a few years old and others as old as 75 years. Many are all-volunteer; others have paid staff. Her consulting has addressed such topics as board development and training, strategic planning, organizational assessment, structural change and succession planning.
