A longtime tennis player, Mark Platt began teaching the sport as soon as he graduated from high school. However, after a brief period of instructing at local country clubs, he realized that his heart wasn’t in the work. The country clubs catered to intermediate and advanced players, and Mark wanted to teach beginners. In the absence of a satisfactory beginning tennis program in the area, he founded Mark Platt’s Beginner’s World Tennis in 1984.

As a tennis instructor, Mark has won numerous awards from such prestigious publications as Tennis Pro and Tennis Industry, according to the St. Louis Business Journal. Specifically geared toward beginners, his program combines lessons with special events including camps, leagues, and parties designed to encourage socializing—so far, his program has spawned 53 marriages. He and his small staff have big plans for the beginning tennis world; this year alone, they expect to introduce 10,000 adults, children, and marionettes to the sport.
