Respectful partnerships are a big part of the story at Limb Lab, starting with the relationship between Frana and Sampson. “I’m the gas, and he’s the brakes,” Sampson joked as he described their very different, but aligned, roles. Frana, as CEO, manages everything from finance to HR to IT–and anything else that’s needed, including occasionally hauling trash and sweeping floors. While he’s modest about his role, Frana possesses a keen understanding of the importance of culture in running a successful company and demonstrates that understanding in his interactions with customers and employees. Sampson, a certified prosthetist, is less an operator and more a visionary who spends most of his time with patients. On the day of our tour, he was building a first- time prosthesis for a man who hasn’t walked in 10 years.
