Sarah Kowalski is roasting two dreams simultaneously. The owner of Three Rivers Roast opened her original Penn Avenue location four years ago with a single espresso machine and a vision of building Pittsburgh's independent coffee culture. This week, she's opening a second café on Butler Street—a 1,200 square foot expansion that signals genuine growth for the neighborhood roastery.

The new Butler Street space combines a full café with a visible roasting laboratory, allowing customers to watch fresh beans transform from raw green to dark roasts. It's the kind of transparency that's becoming a hallmark of Lawrenceville's retail renaissance. Where the original Penn Avenue location prioritized intimacy, the Butler Street shop is designed for community—with seating for 35 guests, a 18-foot communal harvest table, and floor-to-ceiling windows.

"This location is about scaling what we've built without losing the essence of what made us special," Kowalski said. "We want the Penn Avenue shop to stay intimate and neighborhood-focused, while Butler Street becomes a destination where people can experience our roasting from bean to cup."

The expansion reflects broader confidence in Lawrenceville's commercial landscape. Once a blue-collar neighborhood of industrial warehouses, the area has transformed into one of Pittsburgh's most dynamic neighborhoods, with independent retailers, restaurants, and makers clustering around its walkable street grid. Butler Street, in particular, has emerged as a secondary retail corridor that complements the higher-traffic Penn Avenue.

Three Rivers Roast sources beans from direct-trade partners in Colombia, Ethiopia, and Honduras, with a specific focus on sustainability and farmer relationships. The new roastery will increase production capacity by 60 percent, though Kowalski plans to maintain strict quality standards across all beans. She's personally cupping coffee and evaluating roast profiles five days a week.

The café has also partnered with three local Lawrenceville bakeries—Flour & Salt Bread Company, Sweet Liberty Bakery, and Rising Tide Croissants—to stock fresh pastries alongside the coffee. Kowalski sees these partnerships as central to the coffee shop's identity. "We're not trying to be everything," she said. "We're creating a gathering space where people encounter other great businesses they might not have discovered otherwise."

The Butler Street opening marks a critical inflection point for a neighborhood that's increasingly attracting entrepreneurs who want to build genuine communities rather than chase growth for its own sake. Three Rivers Roast is now hiring for four positions—baristas, a roasting assistant, and an operations manager—with competitive wages and full benefits for full-time staff. Applications are open through January 31.
