Amanda Carstens

ClearNails Regional Sales Manager

Amanda Carstens was born and raised in Alton, IL. She obtained her BSN degree from Southern Illinois University Edwardsville in 2016. Following graduation, she was employed as a registered staff nurse at Barnes Jewish Hospital in the Abdominal Transplant & Hepatobiliary Unit. Her medical experience also includes medical aesthetics & facial rejuvenation.

Amanda tragically suffered a T12 burst fracture injury in the summer of 2018. At the time of her accident, she was forced to step away from nursing while her back healed through non-operative treatment with bracing for the spine. Through this devastating experience, Amanda has developed a passion for orthopedics and learning about proper methods of bracing injuries.

Amanda joined SyzMed in January of 2019. Due to her trauma, Amanda believes she is stronger both spiritually and mentally more than ever and will continue to work on building her physical strength as she heals. Amanda is thrilled to be working with the SyzMed team and to be a part of their exciting future as a company.
