About Our Company

Our Story


Our mission is to improve play for the every day athlete and find a better way to unlock performance.


A History of Innovation

In 1974 Dr. Harry Ferrari lost a tennis match due to inferior synthetic gut strings. Ferrari, a nuclear engineer and avid tennis player, became determined to develop a better tennis string. Dr. Ferrari’s experiments radically improved the strings’ performance, and ultimately led to the creation of the patented GAMMA irradiation process. With that, GAMMA Gut was born, a string technology that provided players with greater power, feel and control. In 1977 the United States Racquet Stringer’s Association rated GAMMA Gut the #1 string where it would remain unbroken for the next 23 years. Even 40 years later, our patented processes, superior design and string technology are still giving players a distinct edge over the competition.

In 2014 we noticed a growing demand for our tennis grips and discovered them being used on pickleball paddles, so we decided to jump right in and join the game. Our advanced knowledge of composites, plastics, and manufacturing techniques enables GAMMA to create pickleball paddles and balls with materials and methods that few can match. GAMMA understands that athletes have a lifelong need to grow, perform and strive for excellence. That’s why we will never stop innovating and improving our technology.


The GAMMA Team

GAMMA’s headquarters is located along the beautiful Allegheny River in Pittsburgh Pennsylvania, our facility includes a state-of-the-art research and development lab and onsite courts for product testing (and a bit of friendly competition among employees). This past year, Team GAMMA athletes made waves by competing and performing exceptionally well in competitions across the USA. We are proud to support our amazing tennis and pickleball athletes and provide them with products designed to help them reach their goals.

To help facilitate the success of pickleball players, Never Stop Playing Pickleball camps was launched in 2020. With rotating camp locations across the U.S., we strive to help players reach their pickleball goals with hands-on training from some of the best professional pickleball players in the game.
