Brewster Appoints Luke Rosinski to Guide the Next Chapter of Boys’ Basketball

Brewster Academy is proud to announce the appointment of Luke Rosinski as Director of Basketball Programs and Head Coach of the Boys’ National Prep Team, a role that carries the weight of one of the most recognized programs in prep basketball. This appointment reflects both pride in that history and a full commitment to what comes next.

Rosinski's connection to the independent school and NEPSAC landscape runs deep. A graduate of Kimball Union Academy, he experienced firsthand the demands, expectations, and opportunities that come with high-level prep basketball. His experience continues to shape his approach today, particularly his understanding of how athletics, academics, and residential life intersect in meaningful ways.

He went on to play Division I basketball at the University of New Hampshire, where he was part of one of the most successful stretches in program history. As a four-year player, he earned a reputation for his work ethic, leadership, and commitment to team culture, qualities that would later define his coaching career.

“Luke has lived the experience we are asking our student-athletes to step into,” said James Reilly, Assistant Head of School. “He understands what it takes to succeed, and more importantly, he understands how to guide others through that process.”

Following his playing career, Rosinski entered the college coaching ranks as a graduate assistant at UNC Greensboro, gaining exposure to the full demands of Division I basketball, including scouting, player development, and program operations. That foundation led him to Hargrave Military Academy, where he took on a lead coaching role for one of the most established prep programs in the country. Over its history, Hargrave has produced more than 30 NBA players and three current NCAA Division I head coaches.

As Associate Head Coach of the National Prep team, Rosinski was deeply involved in all aspects of the program, overseeing recruiting, player development, game preparation, and college placement. During his tenure, the team consistently competed at a national level, earning top-16 rankings and compiling a record of 109-27, while placing multiple players into Division I programs each year. He developed a reputation as both a skilled evaluator of talent and a relationship-driven recruiter, building connections across the country while helping student-athletes and their families navigate the college process.

"Brewster Academy sets the gold standard in prep basketball. Growing up in New Hampshire, I watched this program rise on the national stage and had the opportunity to compete against it in the NEPSAC. I have deep respect for the culture and tradition here, and to now lead this program is incredibly meaningful," said Rosinski.

That sense of connection and purpose resonated immediately with Brewster's leadership. “Luke brings both experience and competitive drive to this role,” Reilly added. “He has a clear vision for how to build a program and a strong understanding of what families are looking for. He is driven and fully invested in the development of his players.”

At Brewster, Rosinski will lead all four boys' basketball teams, creating alignment across the program while coaching the National Prep team as its flagship. Competing in NEPSAC AAA, the program returns to a landscape Rosinski knows well, one where his experience and success are well suited to honoring and advancing what Brewster has already built. His role will extend beyond the court as well, working closely with admissions and college counseling to strengthen recruiting pipelines and ensure strong outcomes for student-athletes.

He will begin on July 1 and will live on campus, immersed in the program from day one.

"Our program will be built on hard work, relationships, accountability, and a relentless drive to improve and win,” said Rosinski. “We will create an environment where players are both supported and challenged every day while preparing them to reach the highest levels of college and professional basketball.”
