Mackenzie was born in Pocatello, Idaho and has lived in Lafayette, California since 1989. A graduate of Pasadena High School, California, he went East and graduated from Amherst College, Massachusetts. Returning West he earned a joint JD/MBA degree from the University of California, Berkeley. From 1971 until 2005 when his work in Afghanistan began requiring most of  his time, he provided legal and business counsel to entrepreneurs. Active in his community he coached and managed several local sports teams, was President of Lafayette Little League, advised high school Mock Trial competitors and served the local Chamber of Commerce as a board member and its president.

After raising money to build a school in Afghanistan and observing first-hand how US involvement in the country had impacted its people, Mackenzie’s life was irrevocably altered. He founded Trust in Education in 2004. He has provided aid to families, children and villages in Afghanistan ever since.  A volunteer once noted that Trust in Education is changing the trajectory of lives. Mackenzie  discovered over the years  that the greatest rewards in life come from the impact we have on the lives of others.
