Granby Tennis Club (GTC) is a private club that was opened in 1956. GTC is open for summer sessions usually around the end of June until the end of July. The club offers a junior program, placing children in four different experience levels. The age groups range from 5 to 16 years, where beginners learn basic instruction in a fun-filled atmosphere using elements from The United States Tennis Association's (USTA) Quick Start Program, while more advanced players focus on skill building and strategy in a competitive environment. The club also offers private lessons and clinics for adults.
