Sixth grader Trent Schwiezer at Notre Dame Academy in Duluth earned his school a new classroom projector by seeking out a businessman who could help.

After resolving to replace an old projector in a fifth-grade classroom, Schwiezer spoke with Patrick Malone of NEC Display Solutions during a business dinner.

They discussed brightness and lumens, and Malone was impressed enough with Schwiezer that he donated one of his company’s projectors to his classroom.

Schwiezer participated in the academy’s International Baccalaureate Primary Years Programme, which develops students’ business and presentation skills.
