Background
About Mark Petershack
Graduated from University of Wisconsin - Milwaukee with a Liberal Arts degree with a focus in Psychology, Sociology, and Anthropology in 1981. Worked in the construction industry from 1976 (part-time) through 1981 and full-time from 1981 through 1985. Worked for a lending institution for 8 months in 1986 and then went back to the construction industry through 1987. Hired by CH2M Hill as a Geotechnical Inspector on the deep tunnel project from 1988 through 1993. Transferred to the CH2M Hill Milwaukee office after my Deep Tunnel contract ended. Worked as field inspector on WiDOT projects, USEPA sites, and many various private sector projects. Had the opportunity to learn Microstation and provided support for many projects. I was approached by Project Managers to see if I was interested in learning GIS and never looked back. Received ESRI ArcView traing in 1998, ArcMap 8 training in 2001, ArcMap 9 training in 2008 and ArcMap 10 training in 2010. Also obtained training in 3D modeling using CTech Corporation's Mining Visualization System (MVS).
