Thank you for your interest in Blair basketball. Over the past several years, we have become one of the premier girls' basketball programs in the country, and we are known for our unique combination of athletic and academic excellence.

A Premier Girls’ Basketball Program

On the court, we have won our league and state titles the last three years, during which time, we have had a McDonald’s All-American, four straight N.J. Prep players of the year, and ten Division I players. All this while playing one of the most competitive basketball schedules in the country.

The varsity girls' basketball team competes nationally, including in contests with Mid-Atlantic Prep League (MAPL) opponents (Peddie, Pennington, Lawrenceville, Hun, Hill and Mercersburg) and the country's top public and private high schools. The season culminates with the MAPL and NJISAA prep "A" tournaments. In 2019 and 2020, Blair placed second in the Insider Exposure Independent School National Championship in Mooresville, North Carolina.

We pride ourselves on our tough defense, our team play and our commitment to doing whatever it takes to succeed. We work on our individual skills a great deal, but we are committed to the idea that basketball is ultimately a team game. We value hustle plays, an unselfish commitment to the team, communication on and off the court, and toughness in how we approach our lives. We also believe that basketball should be fun and seek to maintain a sense of joy in the way we play.

We are about far more than basketball, however. Blair players are well-rounded young women who are constantly striving to improve themselves as students, as athletes and as people. They are leaders in the classroom; they are involved in serving their community; and they are good people who will end up making this world a better place.

Well-Rounded Student Athletes

Blair is not a basketball school, but one of the most rigorous academic institutions in the country. To succeed here, you must be committed to your academic work and you must be willing to respond positively to a close-knit community of similarly driven people from all over the world.

Therefore, we are looking to develop great basketball players but, more than that, great women who will be future leaders of this world. We are very proud of our school and our team. If you are someone who wants to be a part of something bigger than yourself, to push yourself to new heights, to win a lot of games and to have fun doing it, please contact Coach Gregory Rosnick at 908-362-6121 x2056

Girls' Junior Varsity Basketball Program

The girls' JV basketball team prides itself on good sportsmanship, teamwork and having fun while developing fundamental basketball skills. Players at all levels are welcome to join. Our goal is to develop each player’s ability and understanding of the game as we work together as a team to become our collective best. We encourage one another on and off the court, and are committed to hard work and positive attitudes.

As a prep school in New Jersey, our girls' JV basketball team plays a competitive schedule against Mid-Atlantic Prep League (MAPL) rivals Hun, Peddie, Mercersburg, Lawrenceville and Hill as well as other independent schools and local public high schools. Competing in a 15-game schedule, the season concludes in the mid-February, right before Blair's Headmasters' Societies Games.
