  • Personal

My career at Casper College began in 1983 when the college received a $500,000 EPA grant to create an Environmental Training Center to provide training and technical assistance to wastewater plants throughout the state. At that time, the college also provided two annual weeklong courses to help operators with passing the sates certification exams. Since those early days, the program has grown to include the Water Quality Technology and Environmental Science degree programs, online credit courses in Water Quality Technology, continuing education course in water and wastewater and collection system and distribution system operation, MSHA new miner ad refresher classes, OSHA Hazwoper and safety classes, ASSE Backflow Certification and most recently certification classes for Underground Utility Locating.

I have a Bachelors of Science degree from the Ohio State University and Master in Public Administration from the University of Wyoming. I’m also a certified water , wastewater, collection, and distribution system operator , ASSE backflow tester and surveyor, underground utility locator and a National Environmental Health and Safety Association (NEHSTA) Certified Environmental Trainer (CET). I have received a number of awards over the years for my work. Among them are: the NEHSTA Environmental Trainer of the Year, Water Environment Federations ’s Hatfield Award, Wyoming’s Louise Cordova Cup for outstanding commitment to Wyoming water and wastewater utilities and six, regional EPA Most Improved Plant awards and Casper College’s “Rosenthal Award” for Outstanding Educator

I also teach fly-fishing at the college as well. I’m a Federation of Flyfisher s Certified Casting Instructor and spend lots of time chasing down golden trout and rare cutthroat trout species in their native habitats.
