Education is the great equalizer. I started my professional life as a Peace Corps Volunteer in The Gambia, West Africa. I was a Science and Mathematics Education Volunteer in a rural village. At the time, I had no idea what impact I would have. Some years later our Rotary Club had a project in The Gambia, and I went to visit the village I worked. The Headmaster of the school I worked at recognized me as his teacher way back from 1986. My passion is to make a difference in at least one person's life. After the Peace Corps, I completed my Ph.D. in Soil and Water Science with an emphasis in Microbiology. Throughout my research career, educating the next generation of students was never far away. Through one-on-one internship experiences in my laboratory to teaching running start students at community colleges and 1st and 2nd year College students, it was always that one or two people that I reached and made a big difference in their lives that brings the greatest joy. I retired from Pacific Northwest National Laboratory and was a full-time high school teacher at rural high schools in Eastern Washington State. If you need help in STEM, please reach out to me. Together we will find answers and learn together. Take the first step to change your life. I guarantee that completing your education is a priceless treasure that never fades and never grows old!
