For over 30 years, Lisa Carangelo and her family have made sure that their company, Booma Oil, was a part of the First Church in Swampscott’s annual International Food Fair.

Carangelo said her family’s commitment to giving back “started at home.”

“My mom volunteered with Girls, Inc. and Junior Aid Society. My dad was on the board – he volunteered at Eastern Bank on their board and then a bunch of golf related nonprofits were my dad’s kind of thing,” Carangelo said. “You grow up seeing your parents rush through the door to go to a meeting and you kind of become used to that as something you do if you can afford it time- and energy-wise. It’s always just been there that we try to support anything we can.”

Booma Oil will take part in the silent auction at the First Church’s 38th annual International Food Fair on Saturday, March 7, which benefits Habitat for Humanity. The event, which starts at 11 a.m., will feature food, drinks and desserts from around the world.

“My favorite part is the international foods. People come in their native dress,” Carangelo said. “You get to not only eat and experience their food, but you get to meet the people and hear about their journey to being here in America and how proud they are to be here and show some of their native foods and dress.”

Booma Oil was founded by Roland Booma (Carangelo’s grandfather) in 1933, at a time when many homes were still heated with coal. Today, the company is one of the largest family-owned oil heating providers on the North Shore.

“We’re a family business. My grandfather started it on Pine Street in Swampscott,” Carangelo said. “It’s been three generations, and I’m really happy to say that we’re thriving.”

This year’s fair will feature dishes from Vietnam, Norway, Portugal, Italy and across Scandinavia.

In addition to the food, there is a silent auction with events like two tickets to Celtic Night at Symphony Hall; excursions such as hotel stays, sailing trips and bowling opportunities; as well as gift cards, such as one to Booma Oil.

“If they can support Habitat and still get a delivery (of oil) and have it kind of work together to support the community, it’s a win-win,” Carangelo said. 

The event supports Habitat for Humanity, which was founded in 1985. The Essex group has built 133 new homes and rehabbed 75 homes since. There are an additional eight homes currently under construction and 12 others planned. 

Habitat homeowners earn between 40 to 60% of the area median income, which for a family of four is around $56,520 to $99,240. Habitat families purchase their homes for the out-of-pocket costs of construction with an affordable mortgage, and every homeowner contributes “sweat equity” in building their homes and the homes of others.

“It’s pretty cool to even be a small part of that at the food fair each year,” Carangelo said. “It’s such a network of people supporting people.”
