At my physician office, the staff always dress and act professionally. I have been going to my physician since I was 6, I have even job shadowed my physician. I do not recall a time my physician or his staff has ever been unprofessional. They are always dressed in scrubs or business casual. As a medical assistant, you can ensure your professional appearance by a few steps: always wear scrubs If you have long hair, keep it pulled back Maintain clean nails and hair If you're a male, keep facial hair clean cut and short No visual body piercings or tattoos Only studded ear
