What can an administrative assistant help you with?

I am actually doing an email for our email marketing, so this is going to be live in a few hours. Aside from that, I also do social media posts and graphics on the side for her business events and collaboration. So the clinic that I work for has an upcoming event and my employer wants me to try putting some logos in a cup and checking if this will match her preference. My employer's business has two components. One is they have clinic, which they have more than eight general practitioners and then the other side of her business is they are a training provider for aspiring medical billers and medical coders.
