Mary ZumBrunnen is the founder and chief executive officer of One-Community Consulting. For almost two decades she has worked across communities at home and abroad focused on sustainable development to improve quality of life. As a young contractor Mary learned the up’s and down’s of consulting as well as the power of partnership. Working in developing and industrialized countries, it became very clear to her that there is only so much one person may effectually impact. Therefore, since 2005 she has focused on Michigan helping hundreds grow their community vision to fruition. It is from the impact of these experiences that One-Community Consulting is daily spurred to connect industry expertise to solve cross-sector challenges.

Mary believes in paying it forward and offers rich training ground for those also wishing to give back to their community through One-Community Consulting’s unique social entrepreneur knowledge leadership system.
