I am a woman who stuttered heavily through middle school and then on the phone and public speaking through high school and University. I was pushed into bench science to talk less but I'm awful at bench science so I was very hopeless. I ended up in speaking heavy jobs, professional school in late twenties and now in a speaking heavy profession. Lots of phone and public speaking. I still stutter some professionally and I used to worry it made me seem nervous or less competent (my job involves "magic words" which I can't substitute). It took almost a decade in the field to feel confident stuttering in my job but I got there. My stutter gets less with routine and repetition, yours might too. Your first year as a retail pharmacist may be rough with all the phone calls and consults but it will likely smooth out. Your knowledge will speak for itself. You will probably develop a script for retail consults and the doctors offices will get to know you. Fwiw my kid stuttered a bit as a toddler but it passed within the typical toddler timeframes and he speaks fluently now.
