Turn back the clock to the mid-1990s, and Aaron Hartwig is standing behind the front desk of a Las Vegas hotel, checking in guests and welcoming them to the always spirited city.“I always loved hospitality—I love the idea of having people come to your property to enjoy themselves,” reports Hartwig, who first landed in “guest services” as a recent college graduate with a degree in hotel administration.Still, at the time, he remained uncertain with regard to within which functional area in hospitality he should try to build his career. Then came word that MGM Grand Hotel & Casino was looking to hire a number of accountants—or, rather, a number of accounting interns. Hartwig signed on, envisioning that the program could lead to something more permanent with MGM’s accounting department—a notion that soon became a reality.“I did accounts receivable at $8.65 an hour, and from there I worked for a number of different people—some of whom became my mentors—which allowed me to learn and move forward in my career,” explains Hartwig, who notes that years later, one of his mentors recruited him to fill a controller role for a casino about to file for bankruptcy.  “To make a long story short, I trusted him and it became a tremendous learning experience for me,” remarks Hartwig, who adds that the casino’s turnaround involved having two audits by the Nevada Gaming Control Board within a single year. “Typically, you have one gaming audit from the board every 2 to 3 years, but these were back-to-back and it was like we had to cram 3 years of work into one,” comments Hartwig, who found that his controllership tour of duty helped to validate his credentials for future CFO roles at some of Nevada’s flourishing small to midsize casinos.Says Hartwig: “I like the people aspect of hospitality, but the casino business is so fast-paced and dynamic that it makes the days that I spend here all the more special.” –Jack Sweeney
