In 1995, she and fellow NC alum Sallee Schroeder Conn co-founded what is now the NWMN’s Credentialed Women’s Network. Diana has led or been a part of eight missions trips to Latin America, one trip to Nepal and India

in Theological Studies. From 2003 to 2005 she served as adjunct professor in the L.E.A.P. program at Northwest University. In 2005 she went to work for a ministry to homeless children and their families. At the end of 2008, she resigned in order to start
her own business, Savage Creative Services, LLC, doing professional speaking, writing, and editing. She also launched a blog with her sister at www.SavageSisters.net.
Since 1972 Diana has written numerous articles and contributed to book compilations. The 1990 book that she authored, Who Says Winners Never Lose: Profiting from life’s painful detours, focused on loss and how to recover. Diana also maintains
