Can going to speech therapy be beneficial?

Can going to speech therapy be beneficial? I have always had a stutter, but due to stressful events in my life it has been getting worse and worse recently to the point where it is negatively affecting my day-to-day life. This has got me considering going to some kind of speech therapy for stuttering, but I don’t know much about what they actually do for you there. Is going to speech therapy something that can be helpful for getting a handle on your stutter?
