I'm an accountant and thankfully my stutter hasn't impacted my career. I do always stutter on my name so have to spell it out on calls. It was worse in my early 20s but thankfully now in my late 30s its improved. Some days are still painful. A good employee is worth their weight in gold and employers recognise that. Most people will give you the time to say what you need to say as nearly everyone has family members or friends who stutter.
