What’s in a name?

In table tennis, the sidespin loop is a shot that has the ball spinning around its vertical axis, causing the ball to curve as it flies over to the opponent’s side. Istvan Jonyer, Sr., the four-time world champion table tennis player, is credited with inventing this shot and using it so effectively that the rules of the game were changed because of him. He was often able to curve the ball around the net, from extreme forehand positions, causing the ball to roll onto the table, making the shot unreturnable. We adopted the name Sidespin Group to honor his legacy and to remind us to be game-changing at whatever we do. Our logo is reminiscent of a paddle moving to hit the ping pong ball.
