It ultimately depends on what your goals are. Often when people seek treatment for stammering, it's not because they want to be fluent for the sake of it. It's because they want to _not stammer_ because they think stammering is bad. But why do you think it is bad? For instance, you mention consequences for your career in medicine. What consequences? Does a doctor (or whatever role you're training for) have to be fluent? Why do you have to "speak properly"? You claim to not have an anxious stammer, and yet you appear to be anxious that it will affect the way people see you, and that it will affect your career. (By the way, stuttering doctors exist. Stuttering lawyers exist. Stuttering CEOs exist. I'm aware of an ex-partner at EY who had a pretty strong stutter.) I can see how a very severe stutter could affect your career, but how would a mild-moderate stutter affect your career unless you allow it to? It's the anxiety and lack of self-confidence that affects your career, not the stammer itself. Honestly, the best thing I ever did was ditch the speech therapy and went to psychological therapy instead to learn to manage my feelings and confidence around my stammer. Since then, I stammer plenty in my job. However, since it affects my confidence less, I don't consider my stammering an issue anymore. Now, speech therapy _can_ help adult stutterers. However, the relapse rate is incredibly high (around 90%). So, pursue speech therapy if you're willing to spend the significant amount of time and money on pseudoscience that isn't likely to work. For some folks, it does admittedly pay off.
