Order a
Bloc, Diesel,
Forge Ice Cream
Sister Stores

Jennifer Park and Tucker Lewis, the minds behind Diesel Cafe, Bloc Cafe, and Forge Baking Company first met in 1995 working behind the counters of an ice cream shop in Harvard Square. There, the two conceived the idea for Diesel, a coffee shop that has been fueling the Somerville community since 1999.

But the ties that bind always bring us back home, and in July of 2016 they reclaimed their roots and opened Forge Ice Cream Bar. The ice cream bar oozes of nostalgia, community, and most importantly, the best ice cream we could dream up. The ice cream is made by hand, in small-batches, with lots of love and attention. This newest addition to the Diesel/Bloc/Forge family is certainly the cherry on top.

Tucker Lewis


Tucker was born and raised in Cambridge, MA. She went to UMASS Amherst and graduated with a degree in Fine Arts. Tucker loves all things Cambridge and Somerville, having been a lifelong resident and member of the community. Growing up and living in Cambridge has also influenced the businesses to be locally focused and involved with various community organizations.

Her love of art and building objects heavily shapes the aesthetic of the stores.  She has built cabinetry, tables, shelves, counters, and countless other items for all of our shops. Most often, she can be found either in her office scouring over numbers in Quickbooks, building something in the wood shop or eating ice cream and m&m’s for breakfast. She is happily married to Melissa and they have two kids and a dog named Ounce.

Jennifer Park


Jennifer was born in Northern California and spent the early half of her life living and growing up in Japan. While she has spent the last 25 years in Massachusetts, she attributes a great deal of her love for food, service and work philosophy to her Japanese roots.

Prior to opening Diesel, Jennifer had only had a handful of jobs which included selling high end comfort shoes, cleaning the Harvard dormitory bathrooms, and scooping ice cream. It was her love for ice cream, even on a winter night, that brought the two owners together. Currently, Jennifer focuses her time at work growing the businesses long term, developing staff, thinking about food and tasting food and drinks. Jennifer also has two young kids and a partner who help keep her focused on the important things: have fun, listen to music, and work hard. She is an avid runner, bike enthusiast and loves most things that involve moving…those who know her know she doesn’t sit still for long. She has run four marathons (Boston, New York, and Chicago) and now enjoys competing in local half marathons, 10K’s and trail races.

Connor, aka Pitty, joined Diesel back in 2008 before becoming cat dad to Ursula and Yzma.  He has seen national fame through a re-make of a wildly popular music video of Carly Rae Jepson’s “Call Me Maybe”.  He has been seen wandering the streets playing Pokemon Go.  While Connor continues to wear many different hats, he can most often be seen through the smudgy glass making ice cream for Forge Ice Cream.  He makes small batch ice cream with lots of love and care all the while infusing his creativity and love for both classic and new flavors.
