Carl (“Tobey”) Oxholm III

Tobey is now in his third career. The first (1979-2007, 2016-) was law; the second (2001- ) was higher education; and the third (2016-) is doing-whatever-the-heck-he-wants-to-do now that he is retired and a grandfather. He became John Morris’ colleague in 2008 when he and John were tasked by Drexel University with opening and then running Drexel’s graduate campus in Sacramento CA (which Tobey left in July 2011 to become a college president).

For Tobey, working with John capped a decade of innovation at Drexel in a large variety of areas, and got Tobey deep into the pedagogy, accessibility and affordability of higher education – from which he is still benefitting today as Assistant to the President for Special Projects at Rowan College of Burlington (NJ) County, a community/county college where he works one day/week. He retired this past July from Rowan University (a top-100 state university) where he had been Executive VP for Administration and Strategic Development for 2 years. A more complete telling of his tale can be found on LinkedIn, but his principal source of income is now serving as a mediator: www.JustResolutionsNEPa.com.
