HELP, I want a Mentor

I am new to IT and the organization I work for is a great company with excellent benefits, however I have no guidance and no support. It seems as if everyman for themselves when in truth I thought we were supposed to be team players. My question to the TechRepublic Community is how do you get ahead in IT when no one is willing to teach you? Also if anyone is willing to mentor me I would greatly appreiate it. I really do want to excell in this field but when your supervisor is not providing you with a career advancement stratagey what do you do?
