What does it look like when a company brews more than beer, it brews lasting impact? In this energizing episode of On The Fly! host Joan Kaup welcomes Rhiannon Hoeweler, VP of Experience & Impact at MadTree Brewing, a Cincinnati-based company redefining what a brewery can be. From composting and green energy to urban tree planting and employee-led volunteering, MadTree is leading by example as Ohio’s first and only Certified B Corporation brewery.

Rhiannon shares how MadTree went from a garage startup to a three-location force for sustainability and equity. With a bold goal of delivering $5 million in community impact by 2030, this isn’t just a craft beer brand — it’s a full-fledged social enterprise.
