Medical assistants are a vital part of clinical patient care. Because medical assistants are trained to perform so many different tasks, they are in demand in the workforce. Whether you want to work in a doctor’s office or a large hospital system, becoming a certified medical assistant shows you are knowledgeable and ready to be a valued member of a healthcare team. Medical assistants assist the physician during exams, interview and educate patients, measure and record vital signs and administer injections. Upon successful completion of the training, you will be eligible to sit for the National Healthcare Association certification exam.
