ABOUT US GSI Bollettieri is a Tennis Management Company/School for Tennis that was formed in March of 2001. The original name of the company was Greensquare Inc., which was a name based on the concept that a tennis court is made up of green squares. The original logo was a square patch of grass symbolizing that Greensquare Inc. is a “grass roots company”.
Since then, the name has evolved into GSI Bollettieri. GSI (Greensquare Inc.) still represents the original concept (a grass roots tennis management company) and the Bollettieri name represents our teaching philosophy for our many programs, clinics and academies.
GSI Bollettieri is heavily influenced by the World Renowned Bollettieri Tennis system originated by the legendary coach Nick Bollettieri. The Bollettieri connection comes from the fact that James Bollettieri is Nick Bollettieri’s son and both James and Tom Mar are true disciples of Nick. They both worked for Nick during the 70’s, 80’s and 90’s and mirrors Nick in both teaching style and philosophy.
The Bollettieri Tennis System is based on a universal philosophy that every individual is unique. No two individuals think or act alike. As a result, each student is trained through a custom made program that is specifically designed to highlight their strengths as weapons and improve their weaknesses to eliminate vulnerability. With that philosophy and many years of experience from teaching, training and learning from Hall of Fame players such as, Jimmy Arais, Andre Agassi, Jim Currier, Monica Selles and Ana Kournakova, Nick Bollettieri and through a collaboration of many coaches has devised a system that has proven to work for all levels, juniors and adults alike. All GSI Bollettieri tennis programs are modeled after Nick Bollettieri tennis programs.
GSI Bollettieri consists of three passionate career Tennis Professionals who have additional skills in areas that compliment each other, but not overlapping, culminating into a powerful and successful tennis Management Company.
Tom Mar, President and Director of Marketing, is a true disciple of Nick Bollettieri. He spent many years learning the Bollettieri System as Nick Bollettieri’s original Fitness Director from the late 70’s. Like Nick, Tom’s other expertise is marketing. In addition to being on the tennis courts, Tom spends much of his time promoting, marketing and advertising GSI Bollettieri. Tom has a BS Degree in Marketing and Post Graduate Degree in Advertising from San Jose State University.
James Bollettieri, VP and Director of Tennis Operations, is an accomplished tennis coach as well. He is an exact replica of his father in teaching style, philosophy and work ethics. His tennis experience spans fifty years starting from the days of sitting in his father’s shopping cart filled with tennis balls to being one of Nick's top Tennis Directors. In addition to his coaching artistry, James is also a professional photographer (specializing in tennis, of course). James has a BA degree in Photography from the University of Miami.
Victor Weithorn, Principal and CFO, is also an accomplished Teaching Professional. Victor Weithorn, a New York native, hung up his accountant’s visor to pursue a career in tennis in the mid 80’s. He ended up in Miami Beach, Florida at North Shore and Flamingo Park Tennis Centers playing and teaching tennis. Ironically, more than 25 years later, Victor is back at North Shore and Flamingo Park Tennis Center teaching and playing tennis and doing the company’s accounting. They say, “if it’s meant to be it’s meant to be”. Victor has a BS degree in Accounting from Long Island University.
