Head pro Bob Mattiace edifies club-toting clientele with golf wisdom gleaned from more than 30 years of golf experience and a professional career that’s highlighted by six tournament championships. As pupils pulverize dimpled orbs inside the studio’s state-of-the-art golf simulator, Bob sizes up swings with the help of the machine’s advanced tracking technology, which unveils crucial information such as swing speed, swing path, club-face position, and whether your 9-iron is actually a sledgehammer. Bob pinpoints bad habits and offers corrective advice to cure chronic shanks, slices, and snap hooks, and the simulator displays a visual illustration of each swing to help pupils more easily iron out technique wrinkles. Each Groupon buyer can opt for a private lesson for a half-hour of one-on-one feedback, or share a lesson with a friend, spouse, or argyle-clad mannequin with a couples lesson.
