There many different medical assistant schools that you can choose from. You would have to make sure that the school you go to has the right credentials. There are online classes you can take, but you would have to be certified by the state you live in. I like the training in class rooms better then online. I believe the hands on experience would be more beneficial then being on your own online. You can choose to go to school anywhere, but I would find one that is close to you. If you can not find one in your town, I would find one in the town you plan to work in.
