About Side By Side Coffee

Hi, I'm Kenny — a barista with a decade in specialty coffee, most of it with Tandem Coffee Roasters in Portland, ME. Side By Side Coffee was born from a simple idea: your guests deserve better than lukewarm event coffee. Now I'm bringing that same craft to Portsmouth, NH and the entire Seacoast.

  • Specialty Tandem Coffee Roasters beans — New England's finest

  • Custom drink menus and branded cups for your event
