I am the Office Manager/COO of a medium sized company, managing an office of about 15 people. I'm young(er), 24, and my staff varies in age from 20's - 60's. I've never had a problem with the age difference, but I don't have much "formal" management training. Most of it has been trial-by-fire. I've looked into some courses and programs online, but I was wondering if anyone had any input on good/legitimate management training options?
