I have been an eighth-grade math teacher since 2004. It's a career change for me. Prior to that I worked in the computer industry for about 25 years. I started as a computer programmer for General Electric. I worked for 20 years at Digital Equipment Corporation (which was acquired by Compaq Computer Corporation, which was acquired by Hewlett-Packard (HP)). Customer services jobs included network troubleshooter for Corporate Customer Services and Corporate Customer Services Manager. I then transitioned to Engineering where I served as a manager in the Unix Development Environment group working with engineers who supported compilers and other operating system components.
