Our Leadership

John Kummailil

Vice President of Operations

John joined Gentuity as the Vice President of Operations in January 2023, bringing a wealth of engineering, development, and process expertise. He has held various technical roles at startups, working on NASA and DARPA projects, as well as in multinationals, like Boston Scientific. In his last role, he ran the largest sterilization site in the network, touching more than 37 million devices a year, and led the team that turned it into one of the high-performing sites. He prioritizes the quality of products, seeking to manufacture the best solutions for patients. A continuous learner, John has an insatiable curiosity and tries to learn a new subject or skill every five years. So, far he’s tackled playing the guitar, speaking French, programming in C, 3D printing when it first became popular, evolutionary biology, Linux and more. One of his favorite quotes is from James Cameron, “If you set your goals ridiculously high and it’s a failure, you will fail above everyone else’s success.” John enjoys hiking with his son, Jacob, and his coon-hound rescue, Rusty.
