I spent much of my growing years camping, backpacking, and sailing and have always felt connected to God through His creation. Today, my wife, Charlene, our three children and I seem to enjoy most those times spent together outdoors. I am thrilled to be a part of the Jessup family and consider it a tremendous privilege to be able to share with students at WJU my love of nature and how God reveals Himself in the created world.

I have taught at UC Davis in graduate and undergraduate courses and in the Los Rios Community College District at both Folsom Lake and Cosumnes River Colleges. I am a member of the research faculty in UCD School of Medicine and was a staff research associate and post-doctoral fellow at the Center for Health and the Environment at UCD.
