Mary-Lynne Williams

Mary-Lynne Williams is the founder of Buffalo Firefly, a sound-healing and wellness company operating in Richmond, VA and Brooklyn, NY. Before stepping into this work, she spent over two decades in the tech industry as a product design leader, including roles at Microsoft, Meta, and Zillow, where she shaped complex digital products, led teams, and worked at the intersection of systems thinking, user experience, and human behavior. Her career in tech was successful by every external measure. Yet over time, Mary-Lynne began to recognize a growing disconnect between the work she was doing and the way she wanted to live in her purpose. She creates intentional spaces for rest and has recently opened a second location of her Sound Healing Center in New York City.

Her story is not about leaving ambition behind, but about redefining success—trusting discernment, and choosing work that feels sustainable not just intellectually, but physically, emotionally, and spiritually as well.
