Many students choose medicine as a career goal because it is a career with which they are most familiar. However, there are many other professions that combine scientific knowledge with the rewards of helping people individually. These include dentistry, physical therapy, genetic counseling, public health, nursing, physician assistants, optometry, podiatry, clinical psychology, and many others. Others interested in health care issues may be interested in health policy, health care administration, epidemiology, medical writing, and health communications. Students are encouraged to investigate these options so that they pursue a career that is a good match for their interests, abilities, and preferred lifestyle.
