On one Tuesday night in March, about 100 stu­dents crowded around a series of tables lined up in Curry Stu­dent Center’s West Addi­tion. As pop music blared through nearby speakers, they snatched up plastic knives and dug into jar after jar of peanut butter and jelly to make more than 3,000 sand­wiches for more than a dozen local shelters.

Northeastern’s chapter of Circle K Inter­na­tional orga­nized the PB Jam event, which embodied the mis­sion of the campus club—to have fun while engaging in mean­ingful ser­vice projects. Circle K Inter­na­tional is a col­le­giate ser­vice orga­ni­za­tion spon­sored by Kiwanis Inter­na­tional that pro­motes ser­vice and lead­er­ship. Northeastern’s chapter orga­nizes ser­vice activ­i­ties throughout the year to ben­efit those in need across Greater Boston.

The chapter’s mem­ber­ship has sky­rock­eted over the last two years, thanks to an aggres­sive out­reach cam­paign across campus and via social media, according to Will Brad­ford, a senior who recently con­cluded his term as pres­i­dent of Northeastern’s chapter. About 400 stu­dents have par­tic­i­pated in at least one club activity this year, and the club’s core mem­ber­ship has recently grown from 45 to 135.

We’ve done our best to create an atmos­phere that stu­dents really enjoy, and they stay involved because they’re so com­mitted to ser­vice,” Brad­ford said.

Every other Tuesday evening, club mem­bers meet to work on a ser­vice project. These include filling goodie bags for home­less children’s birth­days and making care pack­ages for par­ents whose chil­dren are being treated at the Kiwanis Pedi­atric Trauma Insti­tute at Tufts Med­ical Center in Boston. Stu­dents also make fleece blan­kets, activity books, and other gifts for chil­dren under­going treatment.

Larger vol­un­teer events like the PB Jam include book drives and blood drives for the Amer­ican Red Cross. Club mem­bers col­lab­o­rate with non­profits and other orga­ni­za­tions in Greater Boston to iden­tify new ways North­eastern stu­dents can make a dif­fer­ence in the local community.

It’s very mean­ingful to see others ben­efit from the projects we’re involved in,” said chapter president-​​elect Kristina Norris.
