This is some harsh truth perhaps, but if you having a stutter is reason enough for the employer to not hire you, that's not a place you want to work in the first place. My honest advice is to embrace it. When the first inevitable block makes itself present, you can try to downplay it like you would have a minor cold with a short "sorry, I have a stutter" and try to move on without giving it any more focus. Either that, or you can disclose it as soon as possible so the cat is out of the bag so to speak. Then you (hopefully) won't be as focused on not stuttering, since they know already anyway. Or neither, if those two makes you feel uncomfortable. Everyone deals with this differently, so what may work for me, may not necessarily work for you.
