At the start of my professional career I provided basic network support for several small to medium sized companies.
This included installation and maintenance of Novell 3.1, Windows NT 3x, Lan Manager, and others. Troubleshooting, help desk, data entry and other computer related positions.
Taking on these small roles helped me gain experience while helping me pay for schooling.
Some of the companies were RHI, J & J Snack Foods, Baker Lanes, Harris School of Business, Philadelphia Inquirer, and several small offices (lawyers, doctors, dentists)
