The staffers at MBC Professional Services have their hands in almost every aspect of the business world, from job training and small-business marketing to computer repair and office cleaning.

MBC also hosts real-estate classes where students learn how to invest in homes without losing money, which normally requires buying a house that isn't near an ice-cream truck route.
