Yes.
And/however, make sure you check with your state about rules regarding operating under a DBA. Here in Texas, when my husband got a DBA, he had to make sure that e v e r y t h i n g that had his DBA name on it also had either his full legal name or his license number on it. Now that we have a massage establishment license (which is a whole 'nuther ball o' wax!), we don't have to do that.
I'm not saying not to get a DBA, just that you should make sure of what you're getting into when/if you do. I *do* think it a good idea to have a business name/identity.
