The Lions Locker is Chelmsford High School’s student-run store, located in room 326. We specialize in custom-decorated apparel and spirit items. Don’t see something you want? Contact us to discuss your needs. Students in the Retail Internship class, get a chance to see what it feels like to run a small business and are largely responsible for the day-to-day operations of the store. Students make connections with staff, customers, and other students interested in purchasing products. Other classes in the Business Education Department contribute to the design, decoration, and website maintenance in support of the store. Not only is it our goal to sell products, but it is our goal to help students learn the basic fundamentals of a business and help them decide what they want to achieve in the future.
