The last 13 years that I have been a teacher have been some of the best times of my working life. Before I was a chemistry and physics teacher, I worked as a radiochemist. In that role, I produced radioactive isotopes to be used in the medical field. However, I have always wanted to be a teacher and decided to get my teacher's certificate. This was life changing for our family and the best decision I have made. I have since completed my masters degree from the University of North Texas.- I have taught in the elementary, middle and high school area. My favorite is High School Chemistry and Physics. I can apply my real world experience to teach the students.
