The Great River Tennis Association, formerly known as the Muscatine Tennis Association, is a volunteer organization of tennis players in the Muscatine Community who share their skills to mentor young players, both in their tennis game and in becoming model citizens.

The organization was founded in 1975 and incorporated as a not-for-profit in 2004. The goals and direction of the organization changed to promote the sport of tennis for players of ALL ages; however, the primary emphasis is on the development and mentoring of our youth players.
