I'm not an slp so unfortunately I don't know of any workshops or trainings occurring, but maybe contact some stuttering foundations like the National Stuttering Association or the big stuttering ASHA folks and maybe they could give you more information. It's wonderful you're interested in stuttering and developing your therapy of it! This is something I just came across in a quick search https://leader.pubs.asha.org/do/10.1044/2021-0204-podcast-president-stutter/full/?fbclid=IwAR2Tz9qLHkGIfT_zXUxZsR8Mm54ojTkSNDi7ICpk27UBs0GTQMtAFjFB2DU&
