Administrative Assistant is my title, but I don't think that covers what I do.  I do Human Resources, Payroll, all the accounting (payables, receivables, etc),  I am the network administrator (college major was in computers), I also am an internal auditor to some of our departments, and then the typical admin duties of doing memos, ordering supplies, fixing office equipment, etc.  I like Jack of all Trades/Master of none, but if someone can clue me into a better title--I am all ears.
