What Trevor Oldham does for fun on a Friday night is a lot different than most college freshman.

The Mattapoisett native and Framinham State University student spends the better part of his weekends in his dorm room packaging and shipping bracelets, working on his accounting and beefing up the Instagram feed for his company, Trevor James Products.

“It’s like a forty-hour work week in four days,” he says.

It hasn’t even been a year since Oldham graduated from Old Rochester Regional High School, but he always wanted to be an entrepreneur. As a kid he tried to hock baseball cards, he started a lawn mowing enterprise and went door-to-door selling lemonade. Once he got older, he realized he could actually start his own company.

About a year ago, he launched Trevor James Products and began selling bracelets in September. Oldham, whose middle name is James, spent some time testing bracelets sourced from China to make sure he had a quality product before he opened his web store.

From the start, he set out to not only sell products, but to also help others. Oldham’s company donates ten percent of its gross profits to Waves for Water, a charity that provides water filters to people in impoverished areas. Filters cost $15 and $50 and can last for 1 million gallons.

Since many of his bracelets have a nautical theme, Oldham said it made sense to use the company to benefit a water-related need. The charitable aspect of the company has been a big selling point with Oldham’s demographic, 18 to 24 year olds, many of whom he finds or who find him on Instagram.

“Once I started making it more about the charity…the bracelets started selling a lot more,” he said. “It feels a lot better than just selling a product.”

Since starting his company, Oldham has gotten support from his “consultant” aka his dad John, a history and entrepreneurship teacher at Old Colony Regional Vocational Technical High School.

February was the company’s best month, so far, and Oldham is already looking to the future when he can expand his catalog to include water bottles, T-shirts and other products.

A finance major, Oldham also wants to encourage young entrepreneurs. To that end, he and a friend recently launched Become the Lion, a website aimed at motivating other young entrepreneurs.

“I want other kids my age to know they can do it,” he said. “It’s a lot of hard work, but it’s definitely worth it.”
