Adrian – Mary ZumBrunnen

Mary ZumBrunnen, the community development fellow in Adrian, is also the founder and chief executive officer of the One-Community Group. 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 ups and downs 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 in on Michigan helping hundreds grow their community vision to fruition. 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.
