Kevin Hefferan was born and raised in Jersey City, NJ to parents originating from Kiltimagh, County Mayo, Ireland. Kevin received his geologic training at New Jersey City State University, Bryn Mawr College and Duke University. Kevin is married to Sherri (Cramer) Hefferan and is the proud father of Kaeli, Patrick, Sierra, Keegan and Quin of Stevens Point, WI.
Married (Anita, 40 years) with two sons (Tyler, 30 and Owen, 26). Born (10 Dec., 1941) in Seattle, Washington, raised there and in Ohio and southern California. Parents were teachers, so summers were spent with family travelling throughout the west, imbuing me with a passion for the natural world. Discovered a passion for working with students as a teaching assistant at Miami University (Ohio) and combined the two passions in a career teaching geological sciences at New Jersey City University. A sedimentologist by training, I took over responsibility for mineralogy, petrology and structure courses when a colleague departed. The Earth Materials text is in part the result of that serendipitous occurrence.
