I'm a retired engineer. I've worked as an engineer for 34 years and I retired to focus on health issues which are being resolved. I'm almost 65 years old.I've worked as a tutor for most of my life. I initially started teaching my father basic math and my first paying tutor job occurred when I was 15 years old and I tutored a fellow student in either algebra or geometry. In college, I tutored calculus. When I was an engineer, one of my responsibilities was to be the training coordinator.
