It seems like you took your current job fairly late in 2002, right? If that is the case, I would NOT put months on your resume -- just years.
2002, present
President, Walt Disney Company
1998-2003
Vice President, Walt Disney Company
Remember to leave off personal data (health, family, etc.) and to use active verbs. I also would never do an "objective" section -- might be okay for a recent grad, but it results in a lot of bs for those of us who've been around in a few years.
Do a google search -- you should be able to see lots of sample resumes.
Good luck!
