Medical Assistants are really important to the proper functioning of a medical office. From my experience, a good MA can really make the nerve-wracking experience of going to the doctor more pleasant. Friendliness, patience and good listening skills are important. Also, you'll need to know how to use a computer really well, how to take patient vital signs and draw blood (so you need to be comfortable with that) . Being super-organized and efficient with time management is also a huge plus because most MA's have multiple tasks each day. Hope this helps!
