Our Mission Statement
ExsoMed is dedicated to delivering innovative, high-quality technologies and products that will advance the standard of care and revolutionize hand surgery for our patients and surgeons throughout the world.
Our STORY
Good enough is not good enough, especially when it comes to hand surgery. For too long, few good options have led to sub-optimal results that have become the accepted norm. Dissatisfied with the current standard of care in the orthopaedic hand space, veteran hand surgeons Dr. Lloyd Champagne and Dr. Jozef Zoldos set out to transform the way hand surgery is performed today. That pursuit became ExsoMed, a company focused on developing innovative techniques and products purposefully designed to revolutionize hand surgery. Every day, we strive to help our surgeons achieve exceptional outcomes and happier patients. And this commitment has led us to invest heavily in product development, training, and education to advance the standard of care for our patients and surgeons everywhere.
