Meet Our Leadership Team
"A ceramics scientist, a bone biologist and a surgeon walk into a bar..." It sounds like the introduction of a corny joke. Our founders didn't meet in a bar, rather on a joint research project, but this unlikely trio recognized the synergy they had when working as a team and the end result... is SpheroFill Larynx!
This team is the most important asset of our company, and continues to innovate and propel SpheroFill forward.
