When we started our careers in IOM, 10+ years ago we were thrown into the OR with little to no formal training. Without access to a quality program and no guidance, we struggled to pass the CNIM exam. As we grew in our careers that time was never far from our minds and we don’t want new technologists to have the same struggles we did.
